Regex Help

[Roshawn]

Hi,

I'm doing url rewriting with the help of the Regex class. In my web.config file I have my rewrite rules specified. However,
I have a lot of them as I have a dynamic storefront. Here's a sample:

<Urls>
<add key="/Shoes/-pg(\d+)\.aspx" value="/Shoes/Default.aspx?pg=$1"/>
<add key="/Shoes/-t(\d+)\.aspx" value="/Shoes/Default.aspx?t=$1"/>
<add key="/Shoes/-t(\d+)-pg(\d+)\.aspx" value="/Shoes/Default.aspx?t=$1&amp;pg=$2"/>
<add key="/Shoes/-t(\d+)-s(\d+)\.aspx" value="/Shoes/Default.aspx?t=$1&amp;s=$2"/>
<add key="/Shoes/-t(\d+)-s(\d+)-pg(\d+)\.aspx" value="/Shoes/Default.aspx?t=$1&amp;s=$2&amp;pg=$3"/>
........ many more follow but are vastly different ........
</Urls>

Fortunately, these rules work like a charm. But I was wondering if I could somehow consolidate this sample into one or two
rules with the use of regular expressions.

It took me a while to get this working as I don't quite understand regular expressions correctly, so could someone out there
help me?

Thanks,
Roshawn
