Use Appcmd to set IIS compression level

Here are a few commands to set properties on IIS compression.   


‘This was run from cmd.exe
c:windowssystem32inetsrvappcmd set config -section:urlCompression /doDynamicCompression:true
c:windowssystem32inetsrvappcmd set config -section:system.webServer/httpCompression -[name=’gzip’].dynamicCompressionLevel:9
c:windowssystem32inetsrvappcmd set config /section:httpCompression -directory:E:DataIISTemporaryCompressedFiles -maxDiskSpaceUsage:100 -minFileSizeForComp:256
icacls E:DataIISTemporaryCompressedFiles /grant “NT AuthorityAuthenticated Users:(OI)(CI)(M)”


This was run from Powershell.  Note the slight syntax difference.
c:windowssystem32inetsrvappcmd set config /section:urlCompression /doDynamicCompression:true
c:windowssystem32inetsrvappcmd set config /section:system.webServer/httpCompression -[name=”‘gzip'”].dynamicCompressionLevel:9
c:windowssystem32inetsrvappcmd set config /section:httpCompression /directory:E:DataIISTemporaryCompressedFiles /maxDiskSpaceUsage:100 /minFileSizeForComp:256
icacls E:DataIISTemporaryCompressedFiles /grant “NT AuthorityAuthenticated Users:(OI)(CI)(M)”


Properties on the httpCompression section
ERROR ( message:-sendCacheHeaders
-expiresHeader

-doDiskSpaceLimiting

 )


Side note.  I ran into some ‘slight’ syntax issues when running appcmd in Powershell 1.0.  I needed to change the dashes “-” to slashes “/”.   I suppose we’ll look at using the Powershell provider one day,

  1. OR you could simplify by using the compression products from Port80Software[dot]com
    Free trials of httpZip and ZipEnable for IIS are available!

  2. They could do that also. 🙂 For basic compression (both static and dynamic) IIS 7.0 compression works fine. Is there a comparison between the port 80 software and the built-in IIS stuff?
