Subject Re: XSP page getting called TWICE! (was: Pipeline dependencies)
Date Tue, 11 Dec 2001 15:37:25 GMT
I posted this a couple of times here, as well as once to the Dev list.  No one's written back
with any suggestions so far.

I hope y'all don't mind, but I'd like to post this one more time.  It's really stumping me!
 Please help!


Anyone have any thoughts on this?

What could cause an XSP page to get called twice in the same request?

generates the xsl twice, etc.

generation step (not listed) is setting an "attachment" response header ("Content-Disposition:
attachment; filename=myfile.rtf") so that the file will be downloaded instead of displayed
directly in the browser.  Could that be causing this?
