How to redirect all requests except when there's an exact string match

Question

Requirement- I want to redirect all requests that end with /abcd to /products/abcd

This should match all urls such as these-

• /collection/abcd
• /collections/all/abcd
• /hello/world/abcd

This is what i'm using- rewrite /abcd/?$ https://example.com/products/abcd permanent;

The problem- if someone visits /products/abcd, this url also matches the rewrite rule, and goes into an infinite loop.

I also tried this regex, but that doesn't match any url (i.e. no redirects happen)- rewrite /(^products/)abcd/?$ https://example.com/products/abcd permanent;

Answer 1

I found a solution for this, which uses nginx location blocks-

location /products {}
location / {
    rewrite /abcd/?$ https://example.com/products/abcd permanent;
}
