I have a site with thousands of pages that need to be redirected. I was thinking of using a 301 redirect in my .htaccess, but I'm just afraid that this will be very inefficient.
Would having a .htaccess with thousands of lines (there is no way to have a re-write rule, they have to be mapped one by one), mean that every time someone accesses one of our pages, they have to read the entire .htaccess? Is that a bad thing? This sit is in a shared host.
I saw a previous answer here about using RewriteMap. How is that different than having the 301 redirects?
Thanks
