I am integrating an aspx app into an existing asp classic app. I send the 3 required values to the aspx FROM the asp in the query string. The aspx page loads fine but when I submit the aspx page (back to itself), it is not recognized as a postback. The page just reloads like the first time.<BR><BR>Note that if I open a new browser and go directly to the aspx page (using the appropriate query string) the page opens and posts back to itself just fine.<BR><BR>I am not trying to use session vars from the asp classic so I don&#039;t know what the issue is here. In the course of researching this problem, I applied the new sp1 for the .net framework 1.1, with no improvement.<BR><BR>thanks<BR><BR>cpet
