I'm creating on a website using Webform, I'm encountering a problem and would like your help/ideas/solutions.
For some pages, I need to check if the query string contains a specific string, if this query string doesn't exist, empty or isn't a number, I will redirect the current request to another page. I'm able to do this with checking query string in code behind in every pages.
What I would want is just to write a global query string handler to do this for me so I don't have to rewrite the code every time. This global handler would run every time every time there's a request to server, it checks these conditions: - the location of the page being requested - the query string
I couldn't find any documents about this. If anybody knows, please enlighten me! Thanks!
