[Web4lib] 301 Redirects question

[McMorris,Don]

I have never done this, but in theory it should work.
 
I would think that you could create 1 dynamic page and a DB table. 
 
The 1 page would then be copied to the old file locations.  Of course, this would mean 1000 extra files hanging around, but I would hope it would lessen the load on the Apache server (you wouldn't have the 1000 extra entries in the apache conf, effectively a flatfile database of apache's settings).
 
The page would simply look at its own location (IE: the URL), and use this to query the DB table.  The query will return theURL, atwhichtime the dynamic page will create the 301 Moved header and pass it on to the browser.  
 
If the language you use to create the page is unable to directly make the headers, it could simply use the META Refresh command (<META HTTP-EQUIV="Refresh" content="0;URL=$NewURL">).  Of course, the page could use some text saying "The page you are trying to access has been moved to <a href...>here</a>".  This way, if redirects are off in the browser, they have the link.
 
The only other option I can think of is perhaps something in .htaccess files... Perhaps you can do something there.

If you can define the pages you want to redirect in the form of regular
expressions, the Apache RedirectMatch directive might be the thing you need.
