I have a blog were most of the traffic comes with query strings for tracking purposes, which means that query strings doesn't change the content of the site.

As I recently learned - W3 Total Cache & WP Fastest Cache, both don't cache pages with query strings.

The question is - how to make it W3 cache or WP cache cache pages with query string & most importantly make the query strings "ignorable", which means for example: if we have two hits: www.example.com/?t=123 www.example.com/?t=333

both are served as one page from the same cache.

I know that I can add "accepted query strings", but I don't know if it just allows to cache pages with query strings, or it also makes query string ignorable? Also - I think this feature forces pages with query strings to work with disk cache instead of disk: enhanced, which I'd like not to do. So - is there is a solution (it can be with W3 total or WP fastest) that ignores query strings and allow pages with them to get cached - without giving up disk:enhanced?


W3TC "Accepted query strings:" makes listed query strings ignorable: https://github.com/szepeviktor/w3-total-cache-fixed/pull/380

My current list is:


This way these pages:


are served from page enhanced cache as for /page

  • I think this is accepted solution. But if i add parameter "s" (search query) and search something, it returns the homepage. Does it work like that for you too? May 2 '19 at 10:02
  • @MichaelRogers That's right. If you add "s" to the ignorable list then it's just ignored and you get the homepage. I think you do not have to add "s" to the list if you want your search works all right. As you can see I don't have "s" on my list. May 3 '19 at 12:15
  • I realize i didn't want to ignore them. I needed them to be cached. But the option to cache queried string is greyed out. I read it's because i use "disk: enhanced"... May 3 '19 at 14:01
  • I have "Cache URIs with query string variables" enabled with "Page Cache Method" = "Opcode: Alternative PHP Cache (APC / APCu)" May 4 '19 at 20:42
  • Hm. I need that then. But that option is also greyed out. May 8 '19 at 9:40
