- Changes made by editing metabase.xml is ignored by default, unless you
have enabled Edit While Running.
- Changing HcFileExtensions requires restarting IIS for it to take effect.
This should be the only setting you change in the metabase, and can be done
via the commandline.
- gzip.dll does NOT need to be added to Web Service Extensions - such helper
DLLs and ISAPI Filters automatically run when configured because they are
global. Only ISAPI Extensions and CGI EXEs need to be added to Web Service
Extensions because they are per-request.
- Your browser must allow compression by sending an appropriate
Accept-Encoding: header

Hello, I'm not sure if my post is in the right newsgroup, but I think that
my
problem is more IIS specific than to wss.
Because very large JavaScript files are transferred the first time a user
opens a sharepoint site, I wanted to use IIS compression to accelarate the
loading time of ows.js and ie55up.js.
So I made the following steps:
* In Inetmgr -> Web Sites -> Properties -> Service -> Check Compress static
files and application files
* Edit the MetaBase.xml as follows:
<IIsCompressionScheme Location ="/LM/W3SVC/Filters/Compression/deflate"
HcCompressionDll="%windir%\system32\inetsrv\gzip.dll"
HcCreateFlags="0"
HcDoDynamicCompression="TRUE"
HcDoOnDemandCompression="TRUE"
HcDoStaticCompression="TRUE"
HcDynamicCompressionLevel="9"
HcFileExtensions="js htm html txt css htc"
HcOnDemandCompLevel="10"
HcPriority="0"
HcScriptFileExtensions="asp aspx asmx asa"
>
</IIsCompressionScheme>
<IIsCompressionScheme Location ="/LM/W3SVC/Filters/Compression/gzip"
HcCompressionDll="%windir%\system32\inetsrv\gzip.dll"
HcCreateFlags="1"
HcDoDynamicCompression="TRUE"
HcDoOnDemandCompression="TRUE"
HcDoStaticCompression="TRUE"
HcDynamicCompressionLevel="9"
HcFileExtensions="js htm html txt css htc"
HcOnDemandCompLevel="10"
HcPriority="1"
HcScriptFileExtensions="asp aspx asmx asa"
>
</IIsCompressionScheme>
<IIsCompressionSchemes Location ="/LM/W3SVC/Filters/Compression/Parameters"
HcCacheControlHeader="max-age=86400"
HcCompressionBufferSize="8192"
HcCompressionDirectory="D:\Compressed IIS Files"
HcDoDiskSpaceLimiting="FALSE"
HcDoDynamicCompression="TRUE"
HcDoOnDemandCompression="TRUE"
HcDoStaticCompression="TRUE"
HcExpiresHeader="Wed, 01 Jan 1997 12:00:00 GMT"
HcFilesDeletedPerDiskFree="256"
HcIoBufferSize="8192"
HcMaxDiskSpaceUsage="99614720"
HcMaxQueueLength="1000"
HcMinFileSizeForComp="1"
HcNoCompressionForHttp10="TRUE"
HcNoCompressionForProxies="FALSE"
HcNoCompressionForRange="FALSE"
HcSendCacheHeaders="FALSE"
>
</IIsCompressionSchemes>
* Added the gzip.dll as Web server extension
Result:
None of my files is sent compressed to the client
What am I doing wrong? Am I missing something?
Thanks for help in advance
Markus
