Hi Constantin, A couple of questions: 1. Why do you remove the etag? Our web server does gzip for static files, and in that case provides a different etag than the non zipped file. So far I did not see any problem with using the web server directly or behind squid. 2. When using this adapter with squid, does it gzip the file once before it gets into the cache, and then server it as binary directly from the cache without processing on every request, or does it gzip it on every request? If you gzip it once then squid needs to store at least two versions of the file, but it should do that anyway with vary header. More disk, less work for the CPU (a trade of that I found works well for our squid).
