Apache config with rewrite and error document handling

I'm looking for someone with significant Apache proxy experience who can develop a CONF file that includes a rewrite statement that converts Web URLs to local URLs (already written and functioning) but that will allow for the use of relative URLs for search engine and ErrorDocument. In my current set up, with the rewrite in place I can only use absolute URLs to point to the ErrorDocuments. However, this causes the client to receive a wrong return code. See <[login to view URL]~jkorpela/www/[login to view URL]> for background on this task. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) 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 Seller 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. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
