Cloudflare / LiteSpeed Cache Redirect Loop w/ UTM

older versions can be found at the bottom of this page

https://www.ads-software.com/plugins/litespeed-cache/advanced/

I currently don’t even use Cloudflare proxied, just for DNS and the issue is still present. SSL settings are also disabled in Cloudflare which apparently could be a reason why the issue is happening

I do have forced SSL enabled on my server, which may resolve the issue but what happens if someone visits the http version without a redirect? Unsecure

ts because im using cloudflare and litespeed together

Correct, LiteSpeed actually supports adding Cloudflare credentials into the app so this issue shouldn’t be occurring

I haven’t noticed the UTM tags being removed after visiting the site before

What I know so far, is the redirection loop is caused by queried tags (UTM tags), usually from ads or newsletters (possibly for long strings with UTM campaigns, medium, and sources), and a forced SSL redirect loop when LiteSpeed & Cloudflare are used in conjunction even if Cloudflare proxy is disabled. The issue occurs randomly and is resolved once the cache is cleared which leads me to believe it can be resolved by LiteSpeed cache.

Nope, do you recommend installing the older version?

so far so good for me, 4.6 working like a charm, i probably wont ever move from this version.. how did you go?

Still having issues, I just downgraded to 4.6 so hopefully it resolved it for the time being

Fingers crossed the team resolve this issue in the next version

please try this code to theme’s functions.php

it will retain the caching , but only make redirection request to no-cache

add_filter( 'wp_redirect', 'lscwp_redirect_check', 10, 2 );
function lscwp_redirect_check( $location, $status ){
    do_action( 'litespeed_control_set_nocache', 'no cache on redirection' );
	return $location;
}

see if it helps.

Only issues is it’s the site is flooded with traffic from a campaign and it’s set to no cache it could cause the site to go down?

if the redirection was like

domain.com -> domain.com/?utm_xxxxxxxx , I wonder who made that redirection

the cache plugin itself doesn’t redirect , but something else did that but LSCWP cached , unwantedly

and do you see a lot of 301/302 on access log when flooded ?

I assume Cloudflare has something todo with it, because everyone seems to be using it. Mine is completely unproxied though so it’s confusing as towards why it would matter

The loop most likely is http -> https -> http -> https, it has something todo with ssl

okay , now we are getting somewhere

please try search in database and site files on key word http or better https:// and update them to https:// then purge all

I don’t have any that are http, I believe maybe when a link is attached in campaign as https:// it causes an issue

So if I put https:// in a newsletter with utms it would cause an issue

Just to note, most queries are ignored as well via LSC

function lscwp_redirect_check( $location, $status ){
    if (strpos($_SERVER['SCRIPT_URI'], "https://") !== false && strpos($location, "https://") !== false ){
    do_action( 'litespeed_control_set_nocache', 'no cache on redirection' );
    }
	return $location;
}

what about disable redirection cache from https:// to https://

Is this okay?

function lscwp_redirect_check( $location, $status ){
	if (strpos($_SERVER['SCRIPT_URI'], "https://") !== false && strpos($location, "https://") !== false ) {
		if  ( strops($_SERVER['QUERY_STRING'], "utm") !== false ){
	do_action( 'litespeed_control_set_nocache', 'no cache on redirection' );
	}
}
	return $location;
}
