nginx example hdd-cache creates possibility of multiple trailing slashes in url
He, we are using cachify for long time and our prefered method is hdd caching with nginx setup.
works fine but now we found a problem at our server setup, that if we use caching and there is a hit, then its possible that urls could have multiple slashes in URL at the end and its always the same response.... ie: https://domain.com/the-slug/ is cached... then those urls all returns the cached site: https://domain.com/the-slug// https://domain.com/the-slug/// https://domain.com/the-slug////
Thats naturally not very good for duplicate content resons (although canonical helps there already).
my Quickfix now is this solution above your nginx.conf:
merge_slashes off;
rewrite ^(.*?)//+(.*?)$ $1/$2 permanent;
This lets nginx redirect first the multiple slashes before it searches for cached files on hdd.
perhaps you have a smarter solution for it, pls let me know :)
This behaviour is not limited to nginx. It's the same on Apache.
Without the cachify, WordPress automatically redirects to the "single-slash" version.
