Why "HTTP CONNECT" disconnects atfer 15 Mins in few proxy server ???

P: n/a
Hi all,
I am maintaing a persistent HTTP connection using the "HTTP
CONNECT" method , this works fine for many proxies like Squid, ISA ,
etc. But the iPlanet proxy disconnects the conneciton after 15 mins.
It fires the HTTP 501 status code saying " Server Internal Error".

Is there any way the i can overcome this problem and maintain a
persistent HTTP connection or should i reconnect the socket for
certain time interval.

If i should reconnect the socket , is there any standard
implementation or algorithm which i can follow to maintain a
persistent HTTP connection.

ne help will greatly apppreciated.

Regards

Are you sending data in these 15 minutes or is the socket IDLE. If you
are sending data over the connection and the iPlanet proxy is still
answering with 501 then that is either a time-out or a bug in the
iPlanet proxy (you probably already knew that ;). If it is a time-out
then maybe you can try to do something with the keep-alive property
see http://www.io.com/~maus/HttpKeepAlive.html
