Tip: Save your /.htaccess file before you publish the store. If it contains statements not related to Erol, then add the code shipped with this patch manually to your local copy of .htaccess and the .htaccess file in the Web host's root directory. If you can't see the (new) .htaccess file in your FTP client, then add "-a" to the external file mask. If your FTP client transfers .htaccess in binary mode, then add ".htaccess" to the list of ASCII files in the settings. If you upload .htaccess in binary mode, it may not exactly do what you expect it to accomplish.
I don't know when/if Erol will ship a patch for IIS. (As a side note, I can't imagine one single reason why hosting an online store under Windows could make sense. OTOH there are many reasons to avoid hosting of anything keen on search engine traffic on a Windows box.)
