URL Rewrites

[mandarin1]

I have URL that use the following strings:

home.aspx?a=2,0&b=150,1&c=-1,0&d=-1,-1
home.aspx?a=-1,-1&b=-1,-1&c=10,0&d=-1,-1

Using ISAPI, how can i rewrite these rules into:
/2,0150,1-1,0-1,-1.html

Also, are commas seen as spaces by Google? If they are not are there any other solutions?

thanks

Welcome to WebmasterWorld mandarin1.

ISAPI_Rewrite is the tool you want to look for. It is very helpful for rewriting URLs on IIS servers.
