I'm working on writing an app that compares two files on the server. The user selects two data files, uploads them, and are processed. When I upload and process my test files (only a dozen records or so) it works fine. When I go to test w/ real data (11,000+ records) I get the error message the page cannot be displayed. The URL doesn't change while uploading and processing so I'm not sure what's casuing the problem. Any ideas? Thanks.

How big are the files you are uploading? It's possible you are simply falling victim to the request timeout.

The file sizes are about 3.5 - 3.75 meg. Nothing too huge. I can upload one real file and one test file without a problem. It's when I try to upload both real files. I've even tried putting a breakpoint on subroutine that handles all the processes so I could see where the error lies and it's like it skips over it completely.
