IIS compression not applied

[antscode]

We have compression enabled in IIS for both dynamic & static files, however it appears the combined JS file returned from Rejuicer is not gzip compressed.

This is how compression is enabled in our web.config

<urlCompression doDynamicCompression="true" dynamicCompressionBeforeCache="true" doStaticCompression="true" />

When I review the response headers for all of the files returned from the server, all our static & dynamic pages have a content-encoding of gzip, however the Rejuiced file has no content-encoding.

This leads me to believe that the raw JS text is coming down, and not a compressed version.

Any ideas?

Thanks,
Anthony.
