Question

On Page_Load, I have to run code to check a url format. The url can be of the following formats:

http://www.xyzabc.com/DisplayProduct?ID=230  or

http://www.xyzabc.com/DisplayProduct?ID=230&blahblah or

http://www.xyzabc.com/S(yya4h4rf4gjh5eo4uazix2t055)X(1))/DisplayProduct?ID=230

Whenever the url has an ID, I want to create a url in the following format:

http://www.xyzabc.com/DisplayProduct?ID=<the id picked from the url>

Since the code will be run for every page (1500+) in the site, how can i write the best optimized code?

Answer 1

something like this:

int ID = 0;

int.TryParse(Request.QueryString["ID"], out ID);

if (ID > 0)
{
    Response.Redirect(String.Format("http://www.xyzabc.com/DisplayProduct?ID={0}", ID));
}
