Deploying ASP.NET 2.0

[Kevin]

Hi,

Hope someone can help us with this problem. This is our first endeavour
into .NET 2.0 :-)

BACKGROUD INFO:
----------------------
We've built a website using .NET 2.0 and deployed onto our webserver. This
webpage simply calls some web services (built with .NET 1.1) running on the
same web server. The webservice executes SQL transactions to a SQL Server
which sits behind our company firewall.

PROBLEM:
----------------------
Everytime a form is submitted (a web service call happens here), it's trying
to connect to a proxy server which no longer exist!! This was verified by our
network team. (Please see below for error message and stack trace).
OTHER NOTES:
------------------
Numerous pages have been built using .NET 1.1 running on the same webserver
and we've never encountered this problem.

TESTING DONE:
-------------------
To test that it's not something wrong with the webservice, we've built a
simple web page using .NET 1.1 which calls the same webservice, depoyed it
onto the webserver, a request was made, and it was successful.

We've also ran this website in question from a internal webserver, and did
not encounter this problem.

QUESTIONS:
-------------------
1)Is there any differences in the way a ASP.NET page built on .NET 2.0 and
..NET 1.1 makes it's call to a webservice??

2)Where is the ASP page picking up this proxy settings from? ASPNET account??

3)Is there a way to overcome this proxy problem from our ASP.NET code?

Many Thanks,
Kevin

Hi Kevin,

The default proxy settings in .NET 2.0 are a bit different than in 1.x. By
default .NET 2.0 uses the default proxy which is using the IE settings
installed in the registry. Since ASP.NET by default doesn't have access to
those keys it ends up searching around for the proxy settings and fails
which is what's very slow.

Alternately it might be that your app is impersonating and indeed HAS access
to the default proxy settings which are now obsolete. If that's the case
just fire up IE on the server and try to clear the proxy settings.

I reported this a while back but I'm not sure whether this was changed for
release or not. You can add a few settings to web.config to not use Proxy
settings of the machine.

Take a look at this post which talks about this:

http://west-wind.com/weblog/posts/2542.aspx

In the comments there's the web.config settings that worked for me during
the beta. I haven't taken them out, to double check whether it works without
them, but I know those settings worked for me.

Yes, I've added the following lines since I posted and everything works!!.....

<system.net>
<defaultProxy>
<proxy usesystemdefault="false"/>
</defaultProxy>
</system.net>

This was on a release version of .NET 2.0. It's a bit annoying really.......
