Google Crawl Errors Relating to SEO URL rewrite?

You must have those links somewhere. Do you have any page that is outside of the "lingerie/pc/" folder? If so, that's probably the issue.

Otherwise: are you submitting a sitemap? Review the URLs included in the sitemap. If there is an issue, make sure that the code has not been altered, and that the "includes/productcartfolder.asp" file includes the correct folder name.

Our webmaster tools reported broken links that we couldn't find anywhere... I later found out those links are coming from other sites that are linking to us...the problem i think is that googlebot keeps on trying to browse the site with the broken url. The absolute URL's are obviously going to work..... but the relative URL's will continue to be broken.
That's my theory. Do a google search to see if you can find if a site that has an incorrect link to you. We've fixed these using isapi to redirect the original broken link to a fixed one. An example is... a link would come in missing part of the url... in your case its missing the lingerie part

if your links are relative...then it will never put the lingerie back... you need to use ISAPI to automatically add the lingerie back to the url. This is how we corrected the issue. Here is what our code looks like. This is with Rewrite v2. Not sure if it works on the latest version. Basically we are redirecting any url that is completely missing /productcart/pc/, only missing /productcart/ or only missing /pc/ to the correct structure.

RewriteRule /([^./]+\.htm) http://www.abc.com/productcart/pc/$1 [I,RP] RewriteRule /productcart/([^./]+)\.htm http\://www.abc.com/productcart/pc/$1.htm [I,RP] RewriteRule /pc/([^./]+)\.htm http\://www.abc.com/productcart/pc/$1.htm [I,RP]
