Re: [squid-users] Plz help - Connection closing - why?

[Deepa D]

Hi,
   A firewall rule has been set that redirects all the
http traffic for port 80 to another port.The program
of ours which is listening on this port reformats this
url and forwards it to the proxy.It also receives the
proxy's response and passes it on to the browser. 
   Regards,
  Deepa

Please define 'redirected'. It can mean many things.

Hi,
Thanks for the response Robert.I will try and
explain the setup once again :-
All the http traffic from the browser is being
redirected to a program that reformats the url and
sends it to the proxy for further processing and in
turn conveys back the proxy's response to teh
browser.The problem that I am facing is that the
browser displays a "page not found" message even
before the program can convey the proxy's response
back to the browser.
At the proxy end(in the cache.log), I see that the
url is getting processed and a GOT HTTP REPLY HDR
coming in from the remote web server with 200 OK ,
Connection: Close.But this data is not being sent back
to the program.I assume this is because the browser
has already closed its connection.But at the same time
I find the program is still waiting for the squid's
response - it doesn't close its connection with squid.
As per ur suggestion , I will read the HTTP/1.0
specs.Kindly tell me if u can infer anything else as
to what and where the problem could be.
   Regards and TIA,
   Deepa

connection closing is perfectly normal part of operation. Squid is
http/1.0 with a few 1.1 features - but it doesn't support Continue. 

I'm a little unclear on what is going on here, but it sounds like:
1) You are writing a proxy of some sort, using squid to get the data
from the internet.
2) You are having a problem where the connection from squid to your
proxy is closing.

Whats not clear is /when/ it is closing. As I said above, closing the
connection is normal for http operation. If you are coding to the
http/1.1 specification, you should read the section on HTTP/1.0
persistent connection interoperation, and probably the HTTP/1.0 spec
too.

All this sounds pretty normal to me.

Hi,
   I feel the following is happening as the browser is
closing much before the proxy can send back a
response.There is an intermediate program that is
trapping the requests from the browser and redirecting
them to the proxy.I tried sending a 100 Continue
message from the intermediate program , but it doesn't
work.I am working with IE 5.5 browser.
   Please tell me how I can make the browser wait to
receive the response from the proxy.
   Regards and TIA,
   Deepa
