Best way to handle a bad parameter in the url?

[Guest]

Hi;

If the user goes to my page with http://www.mydomain.com/app/page.aspx?ID=5
and there is no data for ID=5, what is the suggested best way to handle this.
I'd like to go to an error page rather than have 2 views in page.aspx, on
just for the error case.

David,

You could just throw an exception and let the normal ASP.NET error handling
catch it. This typically displays an ugly server error page... but if folks
are messing with URLs in unacceptable ways then this is ok.

You could do a "Response.Clear(); Response.StatusCode = 404;
Response.End();"... returning a "resource not found" error (typically "Page
not found") ... though this is a bit misleading.

You could also just redirect to a polite "request not understood" page
(response.redirect()).

Regards,

Rob

Hi David,

I also recommend just throw an application defined exception and let your
error page display a detailed error message that the ID passed on the
QueryString is not found.

I hope this helps. Please feel free to post here if anything is unclear.
