Apache Expert Required

We have three URL rewrite tasks: 1. We have a Magento site and Google has indexed some pages with the SID on the end eg [login to view URL] The SID needs to be removed and an 301 instruction issued. 2. We have multiple language domains that point at the Magento site and Magento then send you to the correct store. EG [login to view URL] [login to view URL] [login to view URL] However if you do this : [login to view URL] you end up on the .[login to view URL] domain but the Italian content. If this mismatch occurs we want a rewrite to correct it eg the above would go to [login to view URL] (domain is the primary) 3. Different site : The site in question has the following format - [login to view URL] Each page also has a title eg Risk Factors. We need a more friendly URL rewrite. We want to extract the article number (eg 1584) and the language (en) and also use the title of the page itself. So in the example given the URL would end up as : ? ? ? ? ? ? ? [login to view URL] We fully SEO our sites and we are constantly looking at ways of improving their visibility on search engines (we know this bit!), but mod_rewrite is tricky for anyone no fluent in it. So, if this job is done WELL then more work is likely to be forth coming. We will release the exact domains and give you .htaccess & other files as required once the bid has been fulfilled. All sites use Apache on Windows Server and have mod_rewrite as standard. We look forward to hearing from you.
