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. CAUTION: You should not use compression if you have an application between the Web server and browser, such as a proxy server or firewall, that does not support HTTP 1.1. Before using HTTP compression, you must make it active by setting the
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 disable HTTP compression as a default or for an individual application, set Compressing Static Content for Windows IISThe 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 in the following example: For instructions on how to set properties on IIS, see your vendor documentation. The example that follows 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 -------------------------------------------------------------- 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 -------------------------------------------------------------- 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. |
