Enable content inspection for compressed content

To enable content inspection for compressed content

In the console tree of ISA Server Management, click General.
In the details pane, click Define HTTP Compression Preferences.
On the Content Inspection tab, select Decompress incoming packets to allow ISA Server Web filters to inspect the content.

Notes

To open ISA Server Management, click Start, point to All Programs, point to Microsoft ISA Server, and then click ISA Server Management.
For ISA Server 2006 Enterprise Edition, expand Microsoft Internet Security and Acceleration Server 2006, expand Arrays, expand Array_Name, expand Configuration, and then click General.
For ISA Server 2006 Standard Edition, expand Microsoft Internet Security and Acceleration Server 2006, expand Server_Name, expand Configuration, and then click General.

Important

When ISA Server Web filters inspect the incoming compressed content, the compressed content will be decompressed. When decompressed, the content is stored in the cache as decompressed text. If ISA Server receives a request for the cached content, it recompresses it before sending, which increases response time.
