Private cache max-age ?

Hello,

Your wiki says to use E=Cache-Control:max-age=60 for 60 seconds public cache and E=Cache-Control:private for private cache.

Both of these work with .htaccess and mod_rewrite rules

Can I set the max-age for private cache in htacess files ?

Or can users only use the server global defined private cache max-age value ?

Thanks

yes. just tested and confirm it works.

Thanks,

How would I do this ? All my tries failed…

for example, in .htaccess,

Code:

RewriteRule \.php - [E=Cache-Control:private,E=Cache-Control:max-age=300]

Code:

RewriteRule \.php - [E=Cache-Control:private]

RewriteRule \.php - [E=Cache-Control:max-age=300]

Thanks,

I was under the impression that those lines would first set the envrionement variable to private and then replace the private setting by max-age=300 thus being the equivalent of only max-age=300…

With Apache's mod_cache, Cache-Control should be set to :

"max-age=300, private"

I've just tested :

RewriteRule \.php - [E=Cache-Control:private,E=Cache-Control:max-age=300]

Code:

X-LiteSpeed-Cache : hit

RewriteRule \.php - [E=Cache-Control:private]

Code:

X-LiteSpeed-Cache : hit,private

hmm ... I'd like to reproduce your result, to find out possible bugs.

what's the cache policy you set ? and any other rewrite rules ?

I did tests only for this simple php:

PHP Code:


		
			
/usr/local/lsws/DEFAULT/html>cat r.php

<?php

echo date("c");

echo "\n";

?>

Hello,

My .htaccess file :

Code:

RewriteEngine On



RewriteRule \.php - [E=Cache-Control:private,E=Cache-Control:max-age=300]

#end of file

I used your r.php script

Cache-Crontrol is an environement variable, if you set it twice it's normal that the second value replaces the first.

You need to be able to set both values seperated by a comma. However I havn't found the correct syntax to do this :

I've tried without success things like this :

Code:

RewriteRule \.php - [E=Cache-Control:'private, max-age=180']

But it gives an error in ls logs:

Code:

ERROR        [[HTAccess]] rewrite: Unknown rewrite rule flag while parsing: RewriteRule \.php - [E=Cache-Control:'private, max-age=180']

My cache is set to :

Code:

Enable Cache : Not Set

Cache Expire Time (seconds) : Not Set

Cache Request with Query String : Yes

Cache Request with Cookie : No

Cache Response with Cookie : No

Ignore Request Cache-Control : No

Ignore Response Cache-Contro : No

Enable Private Cache : Not Set

Private Cache Expire Time (seconds) : 60

Thanks

my test result always:

Code:

X-LiteSpeed-Cache: hit,private

here's one of result:

Code:

I haven't upgraded to LiteSpeed/4.2.2 Enterprise yet (I'm running 4.2.1).

Is 4.2.2 in Release ?

In my WHM interface it says :

Latest Release: 4.2.1

I prefer to wait untill version 4.2.2 shows as an available update in the WHM interface unless the update feature doesn't work and will never show the next version ?
