Hi there.
This looks like a good place to get help with a problem I am having:
- We have a c# windows app, which performs an HTTPWebRequest to a IIS box on
Internet to retrieve an XML response.
- In our test + develop environment this works wonderfully. We have it
working through ISA server and also without ISA server.
- At our client site however, the application times out. This appears to be
caused by Keep Alives.
Here's what's happening when we run at our client site:
- if the IIS server (servicing the HTTP GET request) has Keep Alives
enabled, then our application takes as long as the timeout the IIS has
configured to return. Effectively timing out as our timeout for the request
is set at 30 seconds, and the IIS server has 120 seconds for the keepalives.
(If we change our app to time out after 130 seconds, things work fine).
- if the IIS server has Keep Alives disabled, the request processes as we
expect, within a second or two. Wonderful. However, the owner of the IIS
box is not prepared to leave setting off.
- If we configure our app to not use Keep-Alives, we can't connect out
through our client's proxy server (WebMarshal). We get a 407 authentication
required.
- we have tried various proxy settings and I have tested to confirm this is
configured correctly - trouble is it dunna work without keep-alives enabled
in our app.
Help?!
Without changing WebMarshal configuration, and without changing the remote
IIS server configuration, what can we do to make the request work?
Thanks, Mike.

I've got one database server that works fine when transferring large amounts
of data, but a new one that has been setup seems to want to timeout or drop
the connection after a period of time. I've tried to compare the variables
and they seem to be the same. The versions of MySQL are slightly different
with the good one being 3.23.41 and the one timing out being 3.23.58
Any ideas on what I can check for that would be different or help...

I am able to do this fine with another .aspx page that has no code-behind.
The page that has code-behind throws the exception.

I am programming what is to be a web service client that will use an
HTTP-POST to request and retrieve data. The remote server (written in java
for what it's worth) requires basic authentication as per RFC 2617
(http://www.faqs.org/rfcs/rfc2617.html). My attempts to authenticate are
failing. The server requires the header to be present with the request.
For security reasons, it will not reply in any way if the header is not
present.

I have a WebRequest object that I use to log into a site and then post some
XML. In doing this I set the KeepAlive = true so that it maintains the
connection and does operates undo the initial login.
Is there a way to force this connection to close after I an done with it.
What happens is that I may need to post the XML in several chunks due to
size therefore I cannot set the KeepAlive to False when I post the XML and
