To replace website src content can be done with "content adaption" techniques, using "ecap" etc. However, for your purpose this seems to be far too complicated. (BTW: I have a working solution for this, the purpose of which is to inject ads, to finance open hotspots.) However, in case you have some smart algorithms to analyze web site content on the fly, to check, whether it contains content to be blocked (porn, gambling etc.) or not, then, may be, I can help you :-) Usually, you would have some form of blacklisted sites, so one ACL, using the blacklist and squids.conf "deny_info" directive will do it for you nicely. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/how-i-can-replace-website-source-code-content-tp4665213p4665220.html Sent from the Squid - Users mailing list archive at Nabble.com.
