OsCommerce URL ReWrite

I need to implement a URL ReWrite for an OsCommerce online store. It runs on Apache / PHP / MySql. You can use your own solution or modify an existing OSC addon (SEO-G, Ultimate URL, etc). The addon should be properly commented so other teams will be able to make adjustments. The addon should do the following: 1. The url for the categories, manufactures and products should follow the breadcrumb. So if we have cat1 -> cat2 -> product1 the url should be [login to view URL] 2. The url should be free (invisible) of any GET variables or identifiers (cPath, pID, mID, etc) 3. The default url for categories, manufactures and products should be the name of the category / manufacturer / product BUT it should also be directly editable in admin -> categories / manufacturers etc. 4. The internal divider should be "-". Example: if you have a product "shirt for kids" it should translate to [login to view URL] 5. The url should be cache-able to make the server's life easier. 6. The addon should be easy to turn on / off from the OSC Admin. Same for the cache. ## Deliverables 1) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the worker's Worker Legal Agreement). 2) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 3) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Worker in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. ## Platform Apache/PHP/MySql
