Enabling HTTP Compression for Siebel Web Applications
The use of HTTP compression between the browser and the Web server can improve the performance of Siebel eBusiness Applications over a wide-area network (WAN). Typically, you should consider enabling HTTP compression if a significant number of users access applications over a WAN for which network bandwidth may be a constraint.
The benefit of compression is even greater for users who access applications using standard interactivity, rather than high interactivity, because the latter is already optimized for network use.
However, if your users access applications mostly over a local-area network (LAN), turning on HTTP compression does not improve performance. Instead, it might create performance overhead related to the extra processing needed on both the client and the server sides to compress and decompress data.
HTTP compression is available for all supported Web server platforms without any additional installation. HTTP compression functionality is built into the Siebel Web Server Extension plug-in.
Before using HTTP compression, you must make it active by setting the
DoCompression
parameter in theeapps.cfg
file.CAUTION: If you installed the Siebel HTTP Compression Filter for a pre-7.0.4 release of Siebel 7 eBusiness Applications, then you must uninstall that filter before you enable HTTP compression in this release of Siebel eBusiness Applications. For information, see Uninstalling the Siebel HTTP Compression Filter.
Enabling HTTP Compression
You can enable or disable HTTP compression as default functionality for all applications or selectively for individual applications. By default, HTTP compression is enabled for all applications.
To enable HTTP compression
- Open the
eapps.cfg
file, located in theSIEBEL_ROOT
\SWEApp\BIN
directory, in a text editor.- Do one or both of the following:
- To enable HTTP compression as default functionality, set the DoCompression parameter to
TRUE
in the[defaults]
section. If theDoCompression
parameter is not present, add it.- To enable HTTP compression for an individual application, set the
DoCompression
parameter toTRUE
in the section for that application. For example, in[/callcenter]
setDoCompression = TRUE
. If theDoCompression
parameter is not present, add it.NOTE: Setting a parameter for an individual application overrides the default setting that may appear in the
[defaults]
section. If a parameter is set as a default, then its value applies to all applications for which it is not overridden at the individual application level.- Save and close the
eapps.cfg
file. Changes to theeapps.cfg
file are not active until you restart the Web server.To disable HTTP compression as a default or for an individual application, set
DoCompression
toFALSE
in the appropriate section of theeapps.cfg
file.Compressing Static Content
The Siebel compression filter only compresses dynamic content. For more information about static compression on IIS and instructions on how to enable it, see your IIS 5.0 vendor documentation.
If you plan to compress static Web content in IIS 5.0 on any Web server used for Siebel eBusiness Applications, make sure that you set the IIS 5.0 properties as listed below:
For instructions on how to set properties on IIS, see your vendor documentation.
The example below illustrates a script that you can run on your IIS Web servers to enable static compression after editing it to fit your site requirements.
rem --------------------------------------------------------------
rem run this on webserver site
rem make sure the directories c:\inetpub\AdminScripts\ are correct.
rem --------------------------------------------------------------
c:
cd \
cd inetpub
cd AdminScripts
cscript.exe adsutil.vbs set W3Svc/Filters/Compression/GZIP/HcFileExtensions "htm" "html" "txt" "css" "js"
cscript.exe adsutil.vbs set W3Svc/Filters/Compression/DEFLATE/HcFileExtensions "htm" "html" "txt" "css" "js"
cscript.exe adsutil.vbs set W3Svc/Filters/Compression/Parameters/HcSendCacheHeaders "FALSE"
cscript.exe adsutil.vbs set W3Svc/Filters/Compression/Parameters/HcNoCompressionForProxies "TRUE"
cscript.exe adsutil.vbs set W3Svc/Filters/Compression/Parameters/HcNoCompressionForHttp10 "TRUE"
rem --------------------------------------------------------------
rem Verify the settings
rem --------------------------------------------------------------
cscript.exe adsutil.vbs get W3Svc/Filters/Compression/GZIP/HcFileExtensions
cscript.exe adsutil.vbs get W3Svc/Filters/Compression/DEFLATE/HcFileExtensions
CAUTION: Setting these properties for static compression will affect all applications served on that Web server. Therefore, carefully review your vendor documentation and your site requirements before making a decision to enable this type of compression.
