Looking at number of people reaching my first blog post while searching for information on IIS 7.5, I figured I should do few more posts on changes which are coming in IIS 7.5. In this blog post I am covering new features which have been added to compression and custom errors modules in IIS 7.5.

hi is this the latest version from Microsoft, and what is the difference between this and the 7.0 version?

No. IIS 7.5 won't be available on windows vista. It will only be available on Win7 and Win2K8 R2. Custom errors additions described above will be available on Windows Vista in Sp2.

Hi, I noticed that in IIS7.5 JavaScript is now compressed by default:

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

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

<staticTypes>

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

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

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

<add mimeType="application/atom+xml" enabled="true" />

<add mimeType="application/xaml+xml" enabled="true" />

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

</staticTypes>

</httpCompression>

But in our test, Javascript files are not compressed when enabling both static and dynamic compression. Is there any other factor to set? Let me know if more information needed.

Thanks!
