I just uploaded a new version of the HttpCompressionModule, now called HttpCompress. Please grab a copy and try it out! The big new features for this release are path-based and content-type-based exclusions from compression. Now you can tell the filter to ignore certain files or output types, which is especially handy for things like gif and jpeg output. Hopefully this marks the rebirth of this little project.
If you’re interested, I have a subversion server running now. If you’d like to contribute, let me know and we can talk access. :)
