This question already has an answer here:

I have a server that will have 2 different types/formats of requests coming in. Both request URL's will start with: http://myredirect.mycompany.com/browse/. After '/browse/' it will either be a number:

http://myredirect.mycompany.com/browse/12345, it can be any number

or it will be 2 to 4 capital letters followed by a '-' followed by a number:


What I want to do redirect to a different URL that's based on the incoming URL. For example:

http://myredirect.mycompany.com/browse/12345 would redirect to http://serverA.mycompany.com/show_item.cgi?12345


http://myredirect.mycompany.com/browse/QA-12345 would redirect to http://serverB.mycompany.com/browse/QA-12345

I think what I want is to use an nginx rewrite but I'm not sure how to form. From what I've googled, you can use regex in rewrites so I could use something like


for the first one. But how do I actually pull that number into the redirect URL? Thanks!

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.


Reading nginx's documentation and the PCRE library documentation can help you understand how rewrite and regex work.

For your example you would need a location block wrapping two rewrite rules like this :

location /browse {
    rewrite ^/browse/(\d+)$ http://serverA.mycompany.com/show_item.cgi?$1 [flag];
    rewrite ^/browse/([A-Z]{2,4}-\d+)$ http://serverB.mycompany.com/browse/$1 [flag];

Replace [flag] with permanent or redirect depending on desired redirect code (301 or 302).
