Problem with establishing multiple client request from htc

[Padiamon]

I have used httptunnel-3.3 from
http://www.nocrew.org/software/httptunnel.html for tunneling http
requests which need more than one connection to be tunneled.
My hts is on centos5 server and is listening with hts -F -.-.-.-:8001
5570 command.I have squid web proxy at -.-.-.-:8001.
When i start htc.exe at win32 client (not behind proxy server) the
process created and everything seems OK.
After I open a web page only the first request of http is successfully
established but the others fail to connect.
I want to know how I should implement htc or hts to achieve
establishing multiple http requests the same as specific port such as
ssh which works fine because of
establishing one connection to server.
I would be so thankful.
