Missing cache validator

I’m also getting this same issue.

Hi Chromasia,

We do have etag for it, you may want to check is there any rules may un-tag etag from header in .htaccess file.

Let us know the result of finding the rule.

Best,
Eric

No, not as far as I can see. My .htaccess file is included below.

# BEGIN LSCACHE
## LITESPEED WP CACHE PLUGIN – Do not edit the contents of this block! ##
<IfModule LiteSpeed>
RewriteEngine on
CacheLookup on
RewriteRule .* – [E=Cache-Control:no-autoflush]

### marker NOCACHE COOKIES start ###
RewriteCond %{HTTP_COOKIE} woocommerce_items_in_cart
RewriteRule .* – [E=Cache-Control:no-cache]
### marker NOCACHE COOKIES end ###

### marker CACHE RESOURCE start ###
RewriteRule wp-content/.*/[^/]*(responsive|css|js|dynamic|loader|fonts)\.php – [E=cache-control:max-age=3600]
### marker CACHE RESOURCE end ###

I should add that all the other files required for that page, including a couple of css and js files, don’t have this problem. It’s only the combined css and js files that have the issue.

The ability to ‘Load Google Fonts Asynchronously’ in v1.6.3 is a good addition, and probably makes a significant difference in real world speeds, but it’s added another file to this issue, i.e. both GTmetrix and the Pingdom Page Speed Tool report that “The following resources are missing a cache validator.”

Hi Uniqe_Eric,

Are you still looking into this issue?

Best wishes,

Dave

Hi Dave,

Checked from GT, there are four resources missing a cache validator, but I can not found any from your htaccess file.
So, there are two possible reasons.
1. etag disabled from LSWS->Server->Configuration->Tuning->File ETag
2. etag disabled from apache configuration, and lsws set yes to Using Apache Configuration File

Could you contact your hoster to confirm these two items?

Best,
Eric

Thanks. I’ll ask and get back to you.

Best wishes,

Dave

Here’s the reply …

“Configuration -> Server -> Tuning -> Static File Delivery Optimization -> File ETag is not set, so it’s the default which is to have iNode, Modified Time and Size enabled.

I can’t see FileETag explicitly configured anywhere in the Apache configuration.”

Do I need to ask for it to be turned on?

Best wishes,

Dave

Hi There,

Is there anything else I should check or try? I’d really like to get this sorted out if possible.

Best wishes,

Dave

Hi Dave,

So, there is no FileETag None in Apache config and unset etag in .htaccess.

I didn’t figure out which reason cause the issue now. Could you please create a ticket so we can have a further check on it?

Best,
Eric

Thanks Eric,

I’ve raised a ticket as requested.

Best wishes,

Dave

Finding result:
For some reason, routing through Cloudflare strips the eTag.
