WebLogic Server Proxy Plug-in 12.2.1.0.0 and later version builds are moved from Intel compiler to MSVC Compiler. When Microsoft IIS Web Server is used as a front end with WebLogic Server Proxy Plug-in, the plug-in library depends on the two dlls — msvcp110.dll and msvcr110.dll, provided by Microsoft. These dlls are available with Microsoft Visual C ++ Redistributable Package for x64.

For information about the specific versions of Microsoft IIS Web Server that are supported, see the Oracle Fusion Middleware Supported System Configurations page on the Oracle Technology Network.

Learn about how to install and configure the plug-in for Microsoft IIS Web Server in the following sections:

5.1 Installing and Configuring the Plug-In for Microsoft Internet Information Server

Follow these steps to install and configure the Plug-In for Microsoft Internet Information Server (IIS):

  1. Install Microsoft IIS.

  2. Ensure that all of the necessary features of Microsoft IIS are enabled.

    1. In the Start menu, select Control Panel, and then select Programs and Features.

    2. Select Internet Information Services (IIS) Manager.

    3. Click Turn Windows features on or off.

    4. Expand the entire tree beneath Internet Information Services and ensure all of the sub-features are selected.

      Description of Figure 5-1 follows
      Description of "Figure 5-1 Windows Features for Internet Information Services"

  3. Download and install the latest Oracle WebLogic Server Proxy Plug-In zip file.

  4. Create an iisproxy.ini file with the following content in the %PLUGIN_HOME%\lib\ folder:

        WebLogicHost=URL_of_WebLogic_Host
    WebLogicPort=WebLogic_Port
    Debug=ALL
    DebugConfigInfo=ON
    WLLogFile=C:\Temp\wl-proxy.log

  5. Ensure that the %PLUGIN_HOME%\lib folder is included in the system PATH. (Select Control Panel, select System, select System Properties, select Environment Variables, select System Properties, and then select PATH.

  6. Open IIS Manager. Select Start, select All Programs, select Administrative Tools, and then select Internet Information Services Manager.

  7. Create a new Web Site in IIS. See the IIS Help system for more information.

  8. Click the site name, open Handler Mappings and add a script map (set the Extension to a value such as .jsp, set Executable to %PLUGIN_HOME%\lib\iisproxy.dll, and assign a value to Name).

  9. Click MIME Types and ensure a MIME type has been defined for the extension. Add the MIME type and its definition if it is not present.

  10. Click the site name, open Directory browsing and enable the feature.

  11. Start IIS. Enter services.msc at the command prompt and go to "World Wide Web Publishing Services" at the bottom and restart it. Also restart the web site.

    Description of Figure 5-2 follows
    Description of "Figure 5-2 Windows Services Window"

  12. Test your configuration by sending a request to http://iishost:iisport/application_name/ from the browser and validate the response.

    Here, iishost is the URL of the IIS server and iisport is the port number. Note that the iisport number should be different from the port number of the WebLogic Server.

5.2 Serving Static Files with IIS

After configuring the WLS plug-in and confirming it works (see Installing and Configuring the Plug-In for Microsoft Internet Information Server) follow these steps to serve static files.

  1. Right click Default web site and then click Add Virtual Directory.
  2. In the Alias field enter static and set the physical path to the location of the static files, for example c:\inetpub\wwwroot\static. Click OK. A static folder will appear under Default Web Site.

    Note: The physical path may be different in your case if the files are in a different location. Modify the path accordingly.

    Description of the illustration GUID-F82AB167-41B8-4C1C-B43D-571FA9287728-default.png
  3. Click static under Default Web Site to open the static Home page.
  4. On the static Home page click Handler Mappings and then click View Ordered List on the right-side pane. You will see an ordered list of Handler Mappings.
  5. Click Add Script Map. Set Request Path to "*", set Executable to %PLUGIN_HOME%\lib\iiproxy.dll, and assign the value proxy to Name). Click OK.
  6. Click View Ordered List to re-order the list of handlers.
  7. Click the proxy script map and move it down below the StaticFile handler mapping. (That means the StaticFile handler mapping should appear above the proxy handler mapping.)
  8. Create a static folder under c:\inetpub\wwwroot and copy an HTML file into it, for example index.html.
  9. Restart IIS by restarting the "World Wide Web Publishing Service" under services.
  10. Test your work. Access the index.html file by accessing: http://localhost:80/static/index.html

5.3 Serving Static Files and Dynamic Content From the Same Request with IIS

Suppose you want to serve the static files such as *.gif , *.png images for the request http://localhost:80/console from the IIS and other dynamic content from the backend WebLogic Server. Follow these steps in addition to Serving Static Files with IIS.

  1. Complete the steps described in the Serving Static Files with IIS.

  2. Right-click the Default web site, then click Add Virtual Directory, and then enter the following in the Add Virtual Directory dialog box.

    • Alias—console

    • Physical Path—C:\path_to_the_wls_plug-in\console

    In this example, the physical path to the console is C:\OHS_Plugin_IIS\console.

    Description of the illustration GUID-350B0489-E181-4B81-9F97-112FEBE7FDBC-default.png

    Click OK. You will see a consoleentry in the left pane under the Default Web Site.

  3. Click console under Default Web Site. A console Home opens on the right side.

  4. Click Handler Mappings on the console Home pane.

  5. Right-click StaticFile and select Edit. Update the fields as follows in the Edit Module Mapping dialog box:

  6. Click Request Restrictions. In the Mapping tab of the Request Restrictions dialog box, ensure that Invoke Handler only if the request is mapped to is selected, then select File or Folder. Click OK and OK to dismiss the dialog boxes.

    Description of GUID-E490B51B-80AE-4BC2-BC66-0102D727476D-default.png follows
    Description of the illustration GUID-E490B51B-80AE-4BC2-BC66-0102D727476D-default.png

    The above step is to serve the *.png from the IIS server.

  7. To serve other image files, such as *.gif files, do the following.

    1. Under "Console Home" click "Handler Mappings", then click on "Add Module Mapping" on the right side and then enter the following.

      Request Path—*.gif

      Module—StaticFileModule, DefaultDocumentModule, DirectoryListingModule

      Executable—not required. Keep it blank

      Name—StaticFileForGIF

    2. Click "Request Restrictions". Under "Mapping" make sure the "Invoke Handler only if the request is mapped to" is selected and then select the "File or Folder" and then click "OK" and "OK"

  8. Arrange the order of the handlers.

    1. Click on "console" under "Default web site" and then click on "Handler Mappings" and then "View Ordered List" on the right side

    2. Select "proxy" and move it down till the "proxy" is below the "StaticFile" and "StaticFileForGIF. That is, the order should be like below.

      StaticFile
StaticFileForGIF
proxy

      Description of the illustration GUID-5D142ED8-6FED-45D7-BB9F-24B733C7C0C7-default.png

  9. Copy all of the static files that belong to http://loclhost:<iis-port>/console request from WebLogic Server to IIS.

  10. Restart the service, then restart the web site.

The images (*.png and *.gif) are now served by IIS and dynamic content by Weblogic server.

For example, for the request http://localhost:80/console the images for console are served by the IIS and all other requests other than *.png and *.gif are served by Weblogic Server.

5.4 Using Wildcard Application Mappings to Proxy by Path

You can configure a website or virtual directory to run an Internet Server API (ISAPI) application at the beginning of every request to that website or virtual directory, regardless of the extension of the requested file. You can use this feature to insert a mapping to iisproxy.dll and thereby proxy requests by path to WebLogic Server.

5.4.1 Adding a Wildcard Script Map for IIS

The following steps summarize the instructions available at "Add a Wildcard Script Map" for IIS (http://technet.microsoft.com/en-us/library/cc754606(WS.10).aspx) to add a wildcard script map to do proxy-by-path with ISAPI in IIS:

  1. Open IIS Manager and navigate to the level you want to manage.

    For information about opening IIS Manager, see Open IIS Manager at http://technet.microsoft.com/en-us/library/cc770472(WS.10).aspx.

    For information about navigating to locations in the UI, see Navigation in IIS Manager at http://technet.microsoft.com/en-us/library/cc732920(WS.10).aspx.

  2. In Features View, on the server, site, or application Home page, double-click Handler Mappings.
  3. On the Handler Mappings page, in the Actions pane, click Add Wildcard Script Map.
  4. In the Executable box, type the full path or browse to the iisproxy.dll that processes the request. For example, type systemroot\system32\inetsrv\iisproxy.dll.
  5. In the Name box, type a friendly name for the handler mapping.
  6. Click OK.
  7. Optionally, on the Handler Mappings page, select a handler to lock or unlock. When you lock a handler mapping, it cannot be overridden at lower levels in the configuration. Select a handler mapping in the list, and then in the Actions pane, click Lock or Unlock.
  8. After you add a wildcard script map, you must add the executable to the ISAPI and CGI Restrictions list to enable it to run. For more information about ISAPI and CGI restrictions, see Configuring ISAPI and CGI Restrictions at http://technet.microsoft.com/en-us/library/cc730912(WS.10).aspx.

Note:

If you are proxying a request to multiple IIS applications within the same IIS site, to prevent the subsequent request from proxying to the first website only, create each IIS application and assign a unique application pool to each IIS application.

With IIS 7.x, you cannot assign application pools to virtual directories.

5.5 Proxying Requests from Multiple Virtual Web Sites to WebLogic Server

To proxy requests from multiple websites (defined as virtual directories in IIS) to WebLogic Server:

  1. Create a new directory for the virtual directories. This directory will contain .dll and .ini files used to define the proxy.
  2. Extract the contents of the plug-in .zip file to a directory.
  3. For each virtual directory you configured, copy the contents of the plug-in \lib folder to the directory you created in Step 1.
  4. Create an iisproxy.ini file for the virtual websites, as described in Sample iisproxy.ini File. Copy this iispoxy.ini file to the directory you created in Step 1.
  5. Copy iisproxy.dll to the directory you created in Step 1.

5.5.1 Sample iisproxy.ini File

The following sample iisproxy.ini file can be used with a single, non-clustered WebLogic Server. Comment lines are denoted with the "#" character.

# This file contains initialization name/value pairs
# for the IIS/WebLogic plug-in.
WebLogicHost=localhost
WebLogicPort=7001
ConnectTimeoutSecs=20
ConnectRetrySecs=2

The following sample iisproxy.ini file can be used with clustered WebLogic Servers. Comment lines are denoted with the "#" character.

# This file contains initialization name/value pairs
# for the IIS/WebLogic plug-in.
WebLogicCluster=myweblogic.com:7001,yourweblogic.com:7001
ConnectTimeoutSecs=20
ConnectRetrySecs=2

Note:

If you are using SSL between the plug-in and WebLogic Server, the port number should be defined as the SSL listen port.

5.6 Creating ACLs Through IIS

ACLs will not work through the Oracle WebLogic Server Proxy Plug-In 12c (12.2.1.3.0) for Microsoft IIS Web Server if the Authorization header is not passed by IIS. Use the following information to ensure that the Authorization header is passed by IIS.

  1. Ensure that the user is logged on with local log-on rights when using Basic Authentication.
  2. Grant each user account the Log On Locally user right on the IIS server. To enable the use of Basic Authentication, Two problems may result from Basic Authentication's use of local logon:

    • If the user does not have local logon rights, Basic Authentication does not work even if the FrontPage, IIS, and Windows NT configurations appear to be correct.

    • A user who has local log-on rights and who can obtain physical access to the host computer running IIS will be permitted to start an interactive session at the console.

  3. To enable Basic Authentication, in the Directory Security tab of the console, ensure that the Allow Anonymous option is "on" and all other options are "off".

5.7 Testing the Installation

Follow these steps to ensure that the Microsoft IIS plug-in has been installed, configured, and deployed successfully.

  1. Make sure WebLogic Server and IIS are running.
  2. Save a JSP file into the document root of the default Web Application.
  3. Open a browser and set the URL to the IIS plus filename.jsp, as shown in this example: 
    http://myiis.server.com/filename.jsp

    If filename.jsp is displayed in your browser, the plug-in is functioning.
