Handling ArgumentException: Illegal characters in path

Question

User1880253885 posted

How can I handle URLs with illegal characters such that they don't throw an unhandled exception? I tried an HttpModule but that doesn't catch the error. I'm using IIS6 and .Net 2.0.

Depending on the error message you get, it sounds like an error you can't fix. It sounds like an error thrown by the IIS before any user code is executed, and therefore you cannot handle the error

Any solution for this issue? I am facing same problem.

I got an MVC applciation where in user enters a URL say, example.com/client.site/__.ashx

But if he enters illegal characters like example.com/cleint.site/_||_.aspx

it throws illegal characters in the path. I added global.asax and handled it in application_error and redirecting it to cusotm error page.

If i enter some thing like this:  example.com/client.s||ite/__.ashx, then again the same error is displaying. I want to handle it by redirecting it to custom error page. Any solution please guide me.
