View 7 RepliesI've tried to implement two different solutions that use either and HttpModule or and HttpHandler to do URLRewriting for me. These work great on IIS 7 within my local development environment in Integrated and Classic modes. Currently the production server is running IIS 6.0 on a shared hosting environment. It appears that the request at least hits both the Module and Handler as the URL above redirect to the particular friendly url, but it doesn't redirect and hit hte Module or Handler again. Instead I get a 404 error for the friendly URL.

View 4 RepliesI have introduced site wide exception handling on my site to catch unexpected errors. The event handler sends a message to me when such an exception occurs. But the problem is that any clicks on my site will cause an exception to be thrown with the message: "This is an invalid webresource request."
I googled for an answer and only found a couple of references to 1. setting a fixed machinekey (which for some reason didn't work for me, I got an error saying that the virtual directory wasn't set in IIS, and as far as I know I'm not using IIS at all, I'm using the local development environment and then deploy to a web host) or 2. using a robots.txt file to stop robots from accessing the axd files, but that doesn't help either because it's not robots that cause the problem, anyone clicking around on the page will cause this error. how to solve this problem properly? For now I have handled it by catching and ignoring this particular error by the text in the error message, which works but I would rather fix it so that this error doesn't occur at all.

All the examples and websites i have looked at redirect a user to the error.aspx page when an error occurs. How do you just display a friendly error message on the page the user is viewing saying something like "Sorry unable to do whatever" I've tried using a try catch block on my class that executes a stored procedure and put another try catch on the controller, but this does not work and i still get the default error message (System.InvalidOperationException was unhandled by user code) My code is below:

So how can i just return ViewData["SqlError"] message in page.
I want to show implement Friendly HTTP Error Message feature on server side. Anybody provide appropriate sample to show the custorm error page.

I have an asp.net web application that queries a database with a SELECT query in a stored procedure. If the server returns an error, I want to display a friendly "sorry, there was a problem with your search" type message.
Should I handle this with a custom error page, and a redirect to that page in web.config? Or can put some text in a Label Control and set its property to visible if there are errors? I've seen the latter done with a Try/Catch arrangement in the code behind, but not sure if I can do that here. What would you recommend?
My code behind is below for the page that displays the search results:
