using LiteSpeed_Cache_API in afunction

i want to have the whole page cached, excluding only the hit counter.
i used every possible method but i couldn’t make it, like the example above, once i exclude any part of the page and open it, LiteSpeed plugin serve the page from fresh code resulting in delay.
i’m about to accept this as fact now and display the counter only for admin, making it rebuild cache each hour or so…
thank you.

i try to include the counter.php file which is located in folder “include”
<?php
header(‘X-LiteSpeed-Cache-Control: public, max-age=120, esi=on’);
echo ‘line 1 – cache friendly’;
echo ‘<esi:include src=”/include/counter.php” cache-control=”no-cache”/>’;
echo ‘line 3 – cache friendly’;
?>

and i got this: line 1 – cache friendlyline 3 – cache friendly
the file wasnt included, i try to force error by including wrong file name too, but it didnt fire error message, esi is on in settings but dosnt include files.
🙁
thanx for your help

<IfModule LiteSpeed>
RewriteEngine on
CacheLookup on
RewriteRule PAGE_URI – [E=esi_on:1]
RewriteRule PAGE_URI – [E=cache-control:max-age=120]
and i also used header : header(‘X-LiteSpeed-Cache-Control: public, max-age=120, esi=on’);
i used both methods separately as well
anyway i may try LSCWP API later, thank you for your help
have a nice day
