Hi Ben, thanks for your suggestions. I did analyze tcpdumps only to find out that htc/hts wait at points where a normal browser/http-server continues. The content looks the same on the first sight. It also works perfectly well with Squid in-between. It is designed to work "with proxies". In contrast to other solutions which require the CONNECT-feature activated on the proxy, httptunnel packs the packets into HTTP-GET and HTTP-POST requests which should travel along any proxy. However some proxies buffer the data or open new connections which is something httptunnel cannot cope with. > > Has someone out there successfully got such a setting (httptunnel > > via a proxy) working? Thus, I have to ask more precisely: Has someone got httptunnel work with Apache proxy? Regards, Robert
