Hi, I am again fighting with caching my dynamic content via web proxy. I noticed a *strange* behaivor. I started now debuging my http request headers and saw that (on using Squid) I allways got no "If-None-Match" header. My application sets ETag inside of the response header, so I am wondering, why my application doesn't *see* that header when we use Squid? I tested the stuff without Squid, then all works like expected. My appliction sets in first Response the "ETag" and on second request, we see the correct If-None-Match value for the generated ETag value. am I still missing something? BTW. I am using "squid/2.5.STABLE7-NT" Thanks for any ideas regarding that.
