Sun Java System Web Proxy Server 4.0.8 Release Notes

Release Notes for Sun Java System Web Proxy Server

These release notes contain important information available at the time of the release of the Sun JavaTM System Web Proxy Server 4.0.8 product, hereafter referred to as Proxy Server 4.0.8 or just proxy server. Platform summary and known problems are addressed here. Please read this document and associated documents before you begin using the Sun product.

This document contains the following sections:

Enhancements in Sun Java System Web Proxy Server Releases

The following enhancements have been made in recent releases of Proxy Server:

URL Mapping

URL Mapping has been implemented in Proxy Server 4.0.8, which allows the Proxy Server to act as a reverse proxy. This feature allows Proxy Server to provide a single front-end hostname for back-end application servers. Based on a requester's URI, access is provided to back-end servers.

For more information on URL Mapping, see Reverse Proxy Scenario in Sun Java System Web Proxy Server 4.0.8 Configuration File Reference.

For information on Server Application Functions (SAFs) used in URL Mapping, see Server Application Functions (SAFs) in Sun Java System Web Proxy Server 4.0.8 Configuration File Reference.

Registration with Sun Connection

You can use the Admin Server to register the Web Proxy Server with Sun Connection. Click the Register with Sun Connection button, a client.jnlp application opens up. Follow the wizard to complete the registration.

By registering the Web Proxy Server with Sun Connection you receive the following benefits:

This feature is supported only on Solaris SPARC, x86 and Linux platforms. To avail this feature on Solaris, you need to install SUNWservicetagr and SUNWservicetagu packages in SPARC and x86 systems.

To avail this feature on Linux, you should install the sun-servicetag-1.0.0-1.0.i386.rpm.

Monitoring Server

The monitoring capabilities of Sun Java System Web Proxy Server provides a detailed list of the server parameters that you can monitor at instance level.

From the Web Proxy Administration Server, you can perform the following actions:

ProcedureMonitoring Server

  1. Access the Administration Server

  2. Click the Instance link from the Manage Servers page

  3. Click the Server Status tab

  4. Click the Monitor Current Activity tab

  5. Set the Monitoring Current Activity to ON to monitor the server

    You can also refresh the server in following intervals 5,10 and 15 seconds and view the statistics of the DNS, Keep-Alive, Cache, Server Requests and Work Thread connections.

Embedded DNS Resolution

The embedded DNS supports the non-default name resolution. The DNS client interacts with a DNS server to perform the name resolution. The new SAF dns-lookup, receives the DNS server's IP address as a server argument. This IP address should be added as a DNS directive in the obj.conf file.

In the following example, IP of the DNS server is specified in the server parameter.

<object>
....
DNS fn="dns-lookup" server="170.168.10.3"
...
</object>

In the following example, you can add multiple DNS server IPs to dns-lookup-init, and it will be used in round robin model. In this scenario, do not add DNS server IP to dns-lookup. If DNS server parameters are added to both dns-lookup and dns-lookup-init, the dns-lookup argument will take the precedence.

...
<Object>
...
DNS fn="dns-lookup"
....
Init fn="dns-lookup-init" servers="170.168.10.3, 170.158.10.4"
</Object>

ACL Cache Tuning

The ACLCacheMax is a magnus.conf parameter that sets a limit to the total number of ACLs stored in the ACL cache. There is no default value for ACLCacheMax and it should be configured for a specific limit.

For example, ACLCacheMax 16384

Note –

The ACL cache in this context does not refer to the ACL user cache. It refers to a cache where ACLs are applicable to specific URLs that are cached for performance reasons.

The GCAtStartup is a magnus.conf parameter that allows boolean value. By default the value is false, if set to true, Cache garbage collector clears the garbage during the server startup. This can increase the server startup time when the cache size is high.

The New Directives in the magnus.conf File

This section lists the newly added parameters in the magnus.conf file.

Table 1 magnus.conf Directives

Parameters 

Valid Values 

Description 

FtpPoolSize

1 – 65536

Specify the size of the FTP connection pool. The default value is 256. 

FtpPoolLife

1 – 65536

Specify the life of the connection in seconds, that the FTP connection remain unused in the pool before the monitor thread closes it. The default value is 3600. 

FtpPoolMonitorThread

OFF

Specify the boolean value to monitor the FTP thread functionality. The default is ON.

FtpPoolMonitorLevel

0

Specify an integer value. If set to 0 the pool monitor thread checks whether the connection is dead or alive. 

If set to 1, the NOOP command is sent to the connection and awaits for the reply. Failure to get a responsewill cause the connection to be removed from the pool. The default level is 1.

FtpPoolMonitorInterval

30 – 65536

Specify an integer value in seconds, after which the pool connections are monitored. The default value is 30 

Cache PURGE Feature

Proxy Server allows PURGE requests to clear the cached URL. If the requested URL is purged successfully, a response with an HTTP status code of 200 (OK) is sent by the server. If the specified URL is not cached, a 404 (Not Found) response is sent.

In the following example, the server returns the value 200

bash-2.03$ telnet localhost 8088
Trying 172.9.10.1...
Connected to localhost.
Escape character is '^]'.
PURGE http://foo.com/ HTTP/1.0

HTTP/1.1 200 OK
Server: Sun-Java-System-Web-Proxy-Server/4.0
Date: Fri, 26 Oct 2007 08:15:30 GMT
Connection: close

In the following example, the server returns the value 404.

Connection closed by foreign host.
bash-2.03$ telnet localhost 8088
Trying 172.9.10.1...
Connected to localhost.
Escape character is '^]'.
PURGE http://foo.com/ HTTP/1.0

Daylight Savings Time (DST) will start in USA from the 2nd Sunday of March and end on the 1st Sunday of November. This will impact the date and time rules of the operating system and JRE.  

In the standalone version of proxy server, JRE version compatible with 2007 DST changes is bundled with the installer. However, you need to address the impact on the date and time rules of the operating system by installing the appropriate Operating System patches as explained in step 1 of the Workaround. 

For the JavaES 5 installation of proxy server, you need to install the Operating System patches and also the compatible version of JRE . Follow steps 1 and 2 of the Workaround. 

Workaround

  1. Download and use the appropriate operating system patches. You can download the Solaris patches from http://sunsolve.sun.com/search/document.do?assetkey=1-26-102775-1.

    For other platforms, download similar DST compatible patches from the Operating System vendor's web site.

  2. For Solaris, Windows, and Linux, run proxy server with JRE 1.4.2_13. For HP-UX, run proxy server with JRE 1.4.2.12.

Doc RFE: Proxy Server should not be used with Network Cache Accelerator (NCA). 

When the Proxy Server 4.0.8 is used with NCA, a browser repeatedly prompts for the User ID and password. This happens because NCA does not support Proxy-specific headers like Proxy-authorization.

Workaround

Do not select NCA in the Proxy Listen Socket setting.

Summary  

6205683 

Windows console installation fails. 

6255325 

The installer throws an exception and the installation fails on Linux if the user installs the Proxy Server as a non-root user and the /var/opt/sun/install directory does not exist.

6353576 

Silent upgrade installation does not work. 

6587776 

Proxy Server from Java ES 5 on Windows XP displays system error 1067. 

6607551 

On Windows, uninstalling the patch does not change the Proxy Server version to the previous version number. 

Reverting the patch through Uninstaller script does not change the service description name to the previous Proxy Server version due to RenameService.exe utility limitations. Therefore, even after uninstalling the patch, the service description shows the latest Proxy version instead of the previous version number.

Internationalization

6233090 

A URL with multibyte data (URL encoded) cannot be mapped. 

6253844 

Proxy server online help does not support the language zh-cn. 

6297168 

Starting the server in a different system encoding causes any errors returned by the system in that particular system encoding to be logged in the error log. When viewed through the Administration server, the error log might have characters in system encoding that do not display properly. 

Workaround

Change the browser encoding to match the OS locale so that the error log can be properly viewed through the administration interface. But this will be needed every time you move to other pages and then return to View Error Log again. 

6300080 

Proxy server's content rewriting function is inconsistent.  

6526476 and 6526488 

In a standalone installation of proxy server on HP-UX, the installation in GUI mode results in the display of corrupted Japanese characters (ID no. 6526476). If the installation is continued, it results in error while creating an instance (ID no. 6526488).  

Workaround

You can use either of the following workarounds: 

  • Use the CLI mode of installation for Japanese locale on HP-UX.

  • Continue the installation even with the corrupted display of characters. When the installer fails to create an instance, log in to the administration interface and create an instance.
