Windows SpecificQuestion Regarding RES Files

I am using 2 sv_downloadurl mirrors, one provided by myself via apache and linux, 2 by www.profez.com whom happen to be a windows based hosting company.
now by default, all web url's use a / which is linux based, only windows is grabbing it from a directory which would be a \ needless to say ive had issues with the windows host, and its not MIME file types i added all i needed there. So it is the \ instead of / on windows that i need to get this working?

ex:
"resources"
{
"materials\blah.vtf" "file"
}

instead of
"resources"
{
"materials/blah.vtf" "file"
}
