Multiple Querystring for Url Rewriting Asp.net

How to Handle Multiple Querystring for Url Rewriting in Asp.net


Please go through my earlier article on Url Rewriting.
@Update to my earlier article on Simplest Way to write Url Rewriting

If you have gone through my earlier article

<rewriter>
<rewrite url="~/Article/(.+)-(.+)-(.+).aspx" to="~/DynamicPage.aspx?MyTitleId=$2&amp;CategoryId=$3"/>
</rewriter>

In Web.Config file you can handle special character by replacing it with its code.
Example in our case we have replace & with &amp;

After making changes to web.config file you need to pass third argument as category Id, and that its.  Your code is ready to handle multiple querystring argument.

What if the same page can get just 1 or can get 2 querystrings.

How should the rule be handled ?

PropertyDetail.aspx?PropertyId=5
PropertyDetail.aspx?PropertyId=5&Language=2

Thanks in advance

You need to check that in Page Load Event whether you received a Single Querystring or Multiple Querystring. And based on that you need to perform the logic.

Hi,

can you please provide some idea to write a rewrite rule for the following....


1) www.abcd.com/results.aspx?a=10&b=20

2) www.abcd.com/results.aspx?a=10&b=20&c=30&d=40

first time i'm accessing the page with two query string, then in the same page i'm sorting so i need to pass 4 querystring.

i could rewrite the url for 1. rewrite came.

sameway i wrote for 2, but the rule taken is 1'st rule.

please provide some idea. thanks in advance.

Its a Problem, while dealing with Urlrewriter, the rule are been mapped 1 to 1, and so you cannot map same rule for same page multiple times.

Hi,

I have problem with the updated panel in my project, when am using the rewrite url.

Note:
I am using URL rewriting - This is what I think is causing the problem
The error will occur whenever I choose a selection for a SECOND time. This means that I could select a value from the first dropdown list and get the same error.

Hi,

I have some problem with url rewrite.
Am using the update panels in my project.
Am getting sys.webforms.page request manager server error exception. Unknown error occurred while processing the request on the server.the status code returns from the server was 404.

I am using URL rewriting - This is what I think is causing the problem
The error will occur whenever I choose a selection for a SECOND time. This means that I could select a value from the first drop down box and get the same error (so it is happening on the second postback.).
