Why does IP re-request ASPX page?

[Kwan Lim]

Hi,

Here's the scenario, I have a HttpHandler (.aspx) that generates a xml file
with processing instructions to launch InfoPath as its response.

The problem is that when InfoPath launches it calls the HttpHandler again.

If I save the same xml file instead of open it directly, InfoPath does not
make a request to the HttpHandler.

Does anyone know what's going on?

Hello Kwan,

So your httphandler is processing all files with a .aspx extension? If not, what extension does it target?
Sounds like your response is being targeted by the handler, whereas if you save the file it isn't being processed by the web server. I'd be interested to see more of your code if you have it working; it's something I'd like to be able to do also.

Sorry about the late reply but I didn't think anyone was going to
reply. My httphandler handlers only a specific URL path (i.e.
/filename.aspx).

My current assumption is that InfoPath is trying to perform some sort
of WebDAV operation. Too bad there isn't any documentation regarding
what InfoPath does when it sees the processing instructions.

Regardless, if I ever get the time I'd like to do a little test to
figure this out. I can provide some sample code if you're still
interested.
