Catching report exceptions

Instead of using the Report Manager that comes with Reporting Services, I
have built a custom ASP.NET report interface that launches reports using URL
access. When there is a problem displaying a report, I get the usual
reporting services error, but I would like to redirect to a custom report
page. How do I do that ?

You can use web service Render method to catch an error, but if you want to
use URL approach, than
grab your's url output by using System.Net.HttpWebRequest ( or WebRequest)
class.
If the output is text based (HTML, CSV) - just convert returned by
WebResponse byte array to - char - string and check it for specific error
messages. If the output has to be binary (PDF, EXCEL, etc.) -just check
ContentType of your System.Net.WebResponse class and if it is "text/html" -
the error has occured ( you can always parse byte array to be sure as I
proposed above).
