ESI, Headers, and Cache ratios per quic.cloud

hmmm? I am actually seeing like 57% ratio

that’s normal , when you have QC in front , it will (in most of time) mask the x-litesped-cache header , either x-qc-cache:hit or x-litespeed-cache: hit showing up indicates the cache is working

not exactly , for dynamic one , you may need to check your server access log , to see what they were accessing , some request may not be cacheable , like request to wp-admin/admin-ajax.php which is widely used

The ratio Im referring to is the data magnitude in kb. Which is what I thought would be more important. ( Perhaps not. )

Re: header tags:
@qtwrk In another thread you had written that a lack of an x-litespeed in the header tag meant that that there was no cache at ALL.
Or did I mis interpret what you had written?

Did switching on the ESI somehow cause the x-litespeed tags to disappear? And the x-qc-cache:hit to start happening?

Based on my original query and details am I correct to be using ESI?

no , esi has nothing to do with the header

with QC CDN in front, for dynamic requests, you will see:

x-litespeed-cache: miss + x-qc-cache: miss (cache is not stored in origin and CDN , after this request, it will be stored on both )

x-litespeed-cache: hit + x-qc-cache: miss (cache is on origin but not on CDN, after this request, it will be stored on CDN)

in rare case , you may see

x-litespeed-cache: hit/miss + x-qc-cache: hit

usually when x-qc-cache is present and gives hit , it will mask the x-litespeed-cache header , but as long as you see any of them gives hit , then cache is hit.

when you not seeing any of them , or x-litespeed-cache-control: no-cache that indicates no cache at all

Ok cool. And thank you for your responses.

So in my case. I really dont want to add extra complications, however Id love to understand if ESI is a potential tool I need now, or in the future.

The events I post are all over the world. usually over 4 days when I get bursts of traffic. Thus Im trying to identify if ESI could allow me to obscure the RSS feed from cache. So that they page will stay on the CDN node, or the origin node.

We are going to start to write Google news optimized articles, and Im trying to identify what content I can build into the page. And if I can prevent the rapidly changing content from breaking the cache.

Or I could be wayy off on this line of thinking. Please advise any thoughts. I linked to the 2 types of pages with embeds that I think are busting the cache

the use case for ESI is to make whole page still cached, but certain section of this page , to be no-cache , please check this blog https://blog.litespeedtech.com/2017/09/06/wpw-esi-and-litespeed-cache/

Hi.

Ive read that and every other article I can find on the subject. And it seems it can be applied through modify a shortcode by putting “esi” and ttl=”x” within.

But when I add those to the shoertcode, it outputs the text and does not execute.

so before I ask you to help me troubleshoot. Ive been trying to ask if it is prudent to use on a page like this which has content that get fed via RSS 2x per day. https://xzib.com/miami/news

if it is prudent, can you advise me why its not working when I modify the shortcode.

I do have the crawler running. However I presume this will help keep things on the node for when there is an event outside of the USA(where my server is located)

what kind of text it output ?

it output the text contained within the shortcode. Instead of executing the shortcode

[srr_feed merge_feeds=”0″ count=”10″ visible_items=”10″ color_style=”orange” thumbnail_size=”350px” grid_columns=”2″ thumbnail_position=”cover” thumbnail_force=”always” display_type=”grid” urls=”https://aestheticamagazine.com/feed/” tab_titles=”Aesthetica Magazine” template=”%%thumbnail%% %%title%% %%description%% %%metadata%%” show_date=”1″ show_source=”next_date” show_thumb=”1″ rich_desc=”0″ read_more=”0″ show_author=”1″]

it probably won’t work well with multiple-part-shortocde

if you try a single part shortcode , does it work ?

I use 3 applications of shortcodes.
An event calendar, RSS feed, and instagram.

When I test it to a single part shortcode, the “esi” being added outputs the text. When OI remove it, it works correctly.

Is it possible that it would work with my multi part shortcode with modifications? I would assume the event calendar is

did you enable ESI option ?

yes. Its enabled.

please provide the report number

and also a test page with single shortcode with ESI

The eventon shortcode on this page is the one which displays proper once the ESI is removed.

from report

esi = false

it shows you did not have ESI enabled…
