I'm getting this "Invalid URI: The Uri string is too long ERROR" when redirecting in my custom asp.net 2.0 module using something like Response.Redirect(NavigateURL(TabId) + "&myparam=" & myStrVariable

I have 3 parameters in the query string that I append.  And an example of it is like: "&go=act&userid=140&pol=4150426014".  That is NOT very long at all.  I don't understand why I'm getting this error.  I use NavigateURL(TabId) to redirect back to my own custom module that I'm already in which brings up my master ascx control and I use the query string parameter "go" to determine which ascx control to load. 

Has anyone come across this issue?  Any debugging tips would be helpful.  Thanks!

i've never seen that issue before, and all i could find was this reference http://support.microsoft.com/kb/248061 . I'd recommend that you disable friendlyurl's to get a clearer picture of what path(s) are being written to (AFAIR it's Host>Host Settings... Expand Advanced settings... expand Other settings... disable Friendly URLs )
