Default HTTP 1.1 persistent connection problem
Hi,
I am developing a Http server compliant ot Http 1.1. I am having problems in
maintaining a persistent connection the moment I enable authorization on the
server.the connection is terminated by the client after the authorizing itself
following are the messages exchanged between the server being developed and
IE 6.
Following is what has been captured by Ethereal tool.
When the client requests for /ManojDIR the Server requests for
Authorization information , the clients requests again with the Authorization
information and gets the requested info. All this happens on
168.84.54.156:1516 -- 168.84.54.47:80
Once the client makes the next request it is on a new TCP connection
(168.84.54.156:1517 -- 168.84.54.47:80). Why is that so ?. However , if I
disable authentication every thing happens on the same TCP
Connection(168.84.54.156:1516 -- 168.84.54.47:80).
