Stuck on a Regular Expression...!?

I have the following rule in my web.config that is used in a url redirect

<RewriterRule>

___<LookFor>~/Category/(\w+)\.aspx></LookFor>

___<SendTo><![CDATA[~/Page.aspx?m=13&i=$1]]></SendTo>

</RewriterRule>

This works fine. I'm trying to do a slightly more complex one but I'm having problems with the correct expression and was hoping someone could help.

I'm trying to set it up so it when you browse to /Category/Product/892_23.aspx

It goes to Page.aspx?m=13&c=892&i=23 (eg category 892 and item 23)

The categoryID and productID can be any number of digits, that is why I have put in the '_' so I can see where one ends and the other starts.

What I'm not sure about is how to create the expression that will split them up��

Any help would be great. Thanks

I'm writing this off the top of my head, so I may get it wrong. However, try the following:
<RewriterRule>
<LookFor>~/Category/Products/(\d+)_(\d+)\.aspx></LookFor>
<SendTo><![CDATA[~/Page.aspx?m=13&c=$1&i=$2]]></SendTo>
</RewriterRule>

Thanks for that, that worked first time...

I'm sorry to hyjack my own thread but I have one last question.

I have the following site structure:

SiteRoot/Page.aspx

Page.aspx loads other content pages (ascx) into it based on parameters passed in the querystring.

Eg. Page.aspx?m=1&i=1 would display the "News" module (moduleID=1) and news item 1 (newsID=1)

This works fine. I want to implement URLrewriting. I have followed this articlehttp://msdn.microsoft.com/library/?url=/library/en-us/dnaspp/html/urlrewriting.asp and have hit a problem.
I have set up in my web.config file rules:

<RewriterRule>
___<LookFor>~/News/(\w)\.aspx</LookFor>
___<SendTo>~/Page.aspx?m=1&i=$1</SendTo>
</RewriterRule>

This works fine so when I type MySite/News/1.aspx into the browser it rewrites to MySite/Page.aspx?m=1&i=1 and shows the page.

The problem is the images on the News Item page. They have <img src='images/image1.jpg'> this shows fine on MySite/Page.aspx?m=1&i=1 (Page.aspx is on the root). However when I go to MySite/News/1.aspx, the source for the image is broken. It is now looking for the images folder in the News folder which does not exist.

Do I have to put <img src="http://pics.10026.com/?src=~/images/image.jpg" runat='server'/> on every image reference, or is there another way around this.

Thanks again

Yes, I approved your new thread wherein you asked the same question.
I didn't provide an answer, because frankly I don't know how other developers deal with this problem. To me, adding a tilde to the start of all links would be a royal pain. If you would like to see how I deal with this problem, please see my reply in the following thread:

Stuck, trying to redirect after binarywrite

I thinking that once the pdf page has opened all code in the parent page stops executing until user clicks on page again. Is there some what to redirect after response.close() had done.

Response.ContentType =

"application/pdf";

Response.BinaryWrite(buffer);

Response.Flush();

Response.Close();

Respones.Redirect(

"main.aspx");

You cannot redirect after you close the response. Remove the line of code that says Response.Close(); and your code should work fine.

Don't forget to mark the most helpful post asAnswer for the sake of future readers. Thank you

The suggestion of commiting out the Response.Close() didn't work or maybe there something else I need to do, I'm thinking maybe a timer would work here. Anybody have any other suggestions.
