Our company is changing web platforms and we would like to be able to preserve our Google results so we are planning on putting the 301 redirects into our htaccess file.
My concern is that if if I put in all these redirects (probably 3000 – 5000 total) it will slow the server down as it makes all those checks.
Does anyone know if having an htaccess file this large will cause any problems? I have a pretty fast server for the site (8 cores) so I have a fair amount of horsepower available.
I doubt it would noticeably slow down the server. But check it out first.
Create a .htaccess 5k line file in www/temp folder with some rewrite rules like you will be using. See how long it takes to access a page with and without the .htaccess file.
