Question
Apache rewrite rule for specific subdomain and file types

Asked by Brendo Ross
Hi lads,
I’m in need of some help with a tricky Apache rewrite situation I’m facing. I have multiple subdomains and subdirectories with various access requirements, and I want to create a rewrite rule that satisfies a couple of conditions.
Basically, if :
- the request comes from the subdomain
subdomain.example.com - the requested URL path starts with
/files/. - the file extension is
.pdfor.jpg. - the filename starts with a
public_prefix.
If all the above conditions are met, the request should be redirected to a separate domain https://public-files.example.net/.
I’ve tried the following rewrite rule:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^subdomain\.example\.com$
RewriteCond %{REQUEST_URI} ^/files/public_.*\.(pdf|jpg)$
RewriteRule ^/files/public_(.*)\.(pdf|jpg)$ https://public-files.example.net/$1.$2 [R=301,L]
ofcourse with my domains but it doesn’t work. I believe it might be conflicting with other rewrite rules in my configuration.

Heya,
I’ve looked into your rewrite rule, and it seems mostly correct. However, there are a couple of things that could be improved to make it work as expected. Here’s an updated version of the rule:
I removed the
RewriteCondfor the%{REQUEST_URI}because it’s not necessary since the RewriteRule pattern will only match if the conditions are already met. I also simplified theRewriteRulepattern and included thepublic_prefix in the replacement URL.I’ve tested it on my end and it works as you’ve described but do let me know how it goes with you
