Using IIS7 URL rewrite module, I am trying to get the value of a specific query string parameter, and if it exists I need to get the value of that parameter.
Example URL :
test.aspx?F5REDIRECTION&SearchType=HeaderSearch&hiddendims=&Keyword=tshirt&nkw=1&vsp=2
I need to check if "Keyword" parameter exists and I need to get the value "t-shirt".
If I test run this pattern :
^.*F5REDIRECTION&SearchType=Header.*Keyword=(.*)$
the result is "tshirt&nkw=1&vsp=2"
How do I get only "tshirt"?
Try something like this:
(?<=\?|&)Keyword=(.*?)(?=&|$)
Or if lookarounds aren't available:
(?:\?|&)Keyword=(.*?)(?:&|$)
