Hello All, I have a reverse proxy in place here for some time now and everything is running smoothly. I havent had a single problem in almost three years over various versions. At present I am using 2.7Stable-3 that comes with Ubuntu 8.10. I use a few acls to fine tune access to the proxy. Specifically I use the the browser acl to deny requests based on a file containing certain browser strings and a url-regex to deny certain keywords. However I would like to know if it is possible to finetune things a bit more? Specifically is it possible to examine the content a client is sending using a POST request? Or is there a plugin that can do this? It is probably better to give you a specific example. There are several wordpress blogs on one of the backend servers that recieve quite a few attempts at comment spamming and trackback links. While they do get filtered by anti spam solutions on the backend servers, I would like to block them at the proxy level if possible. They all tend to have the same POST content such as names of various pharmaceuticals etc. Is this an option using Squid? Regards Frog..
