Hello,

This is nice to know, for IIS7 about the compression. But I have one question for this, if you could provide me an answer that would be greate, and I really appriciate that.

i tried to use http compresion on IIS7, but somehow, i guess that dose not give me any result.

I tried to access my website using the folllwing webtools.

www.port80software.com/.../compresscheck.asp

which always shows me, Compression Status : notcompress [:(]

So, i guess something more we need to do httpCompression in IIS7.

Please look into the following what i wrote in my web.config file.

<system.webServer>

<httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files">

<dynamicTypes>

               <add mimeType="text/*" enabled="true" />

               <add mimeType="message/*" enabled="true" />

               <add mimeType="application/x-javascript" enabled="true" />

               <add mimeType="*/*" enabled="true" />

           </dynamicTypes>

           <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" />

</httpCompression>

       <modules>

           <add name="URLRewriter" type="ILink.Beonit.HTTPModules.URLRewriter, ILink.Beonit.HttpModules.URLRewriter" preCondition="managedHandler" />

           <add name="Authentication" type="ILink.Beonit.HTTPModules.Authentication, ILink.Beonit.HttpModules.Authentication" preCondition="managedHandler" />

           <add name="ModuleRewriter" type="ILink.Beonit.HTTPModules.ModuleRewriter,ILink.Beonit.HTTPModules.URLRewriter" preCondition="managedHandler" />

           <add name="ImageServer" type="ILink.Beonit.HTTPModules.ImageServer, ILink.Beonit.HttpModules.ImageServer" preCondition="managedHandler" />

       </modules>

       <handlers>

           <add name="ajax/*.ashx_POST,GET" path="ajax/*.ashx" verb="POST,GET" type="Ajax.PageHandlerFactory, Ajax" preCondition="integratedMode,runtimeVersionv2.0" />

       </handlers>

       <validation validateIntegratedModeConfiguration="false" />

       <httpRedirect enabled="false" destination="http://www.beonit.net" />

       <urlCompression doDynamicCompression="true">

</urlCompression>

   </system.webServer>

I am awaiting for your reply

When you say "the main thread", do you mean a request thread, or the main IIS service thread?

One compression thread per app pool, or many?

Thank you very much for the information, it is very helpful to understand how much it has changed from IIS 6.0!

I think that removing the various knobs is a mistake. Setting a good default value and leaving the knobs available would be my preference.

As for:

HcPriority is removed as scheme to use when multiple ones appear in Accept-Encoding header of request is picked depending on scheme which is appear first in Accept-Encoding header (assuming no q factor). This is as per HTTP specs.

It may be true that the client can specify a preference, and the preference is in presentation order, but, the server administrator may have a different preference. That is why it is stated as a preference order. And yes, there are good reasons for picking one over the other in specific circumstances.

Danke

hi ;

We have a very busy server and IIS Compression disables mostly in daytime. We want it to be open what ever it costs. Because of not being want to consuma that much bandwith.

We even did make

dynamicCompressionDisableCpuUsage="99"                                  dynamicCompressionEnableCpuUsage="1">

But how can I complettly shut of the disabling system ?

Thank you very much

Para utilizar mas eficientemente el ancho de banda disponible, usted puede activar la compresi&oacute;n

GZip/Deflate compression will compress the response payload from the IIS web server to the browser. Pages

Thanks for this fresh information; I was looking for a convenient place for compressing heavy video file. Besides these, I have found another place to compress and decompress all sorts of files. That is http://www.krunchit.net where you can zip or unzip ten files online altogether.

A Better HTTP Compression Solution

Here is a better solution that works with JavaScript and also compatible and with AJAX enabled content: micromighty.com/.../HTTP_Compression_Module.aspx

This HTTP Compression module uses configureable MIME types and other features that are not being offered by any other http compression software, it is also being configured through the Web.config and not on IIS,

See how flexible it can be: micromighty.com/.../HTTPCompressionModule.aspx
