Application hangs creating MSXML2.XMLHTTPClass

Application hangs creating MSXML2.XMLHTTPClass

am 24.02.2007 18:39:00 von Robert Faulkner

I have an asp.net web application that posts either GET or POST http requests to another asp.net web application. I am using impersonation (domain account) in the 'Client' Web app. The Client and Server Applications currently reside on the same server And within the same application pool (using the Identity of a domain account). When deployed, they will reside on different servers. Using Windows Server 2003 Standard & IIS 6.0.

When 'Server' application is set to accept Annonymous (default account) and Window Authentication the 'Server' application hangs when attempting to create & instantiate a MSXML2.XMLHTTPClass object. [This is what I will need in production]

When 'Server' application is set Window Authentication only, IIS on the 'Server' denies access to the application even thought I have not altered the default Web.config settings.

Any ideas on why the MSXML2.XMLHTTPClass object cannot be instantiated? This does not occur when both apps or on my dev machine [in Default app pool].

Hi,

The explanation for your situation is here:

Solution: use ServerXMLHTTP not XMLHTTP.

Cheers
Ken

Ken - A Belated reply. I was pulled onto another project so not able to get back to this until now. Thanks for your assistance. I made the changes as per the directions on you blogg and it worked a charm. Still had a problem however - as intitially I was was calling a web app outside the firewall which in turn calls a web app inside the F/Walll which then calls a web service. Now the web app outside calls direct to the web app inside the firewall.
