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.

Thus, I have to ask more precisely:

Has someone got httptunnel work with Apache proxy?
