[Resolved] expires header not working for js/png files unless htaccess is in place ?


Well-Known Member
Currently on 4.0.16 previously don't recall having this issue though. On test install of vB4 forum the javascript and png files are NOT setting the expires header at all but css and text files set it correctly. But if i add in .htaccess the line BELOW, then it works and sets expires header for png and js files.

ExpiresActive On
site is on subdomain i.e. host2.domain.com

The problem is prior to this i didn't have to do this, so what's changed ? Something in WHM conflicting ?


not working

with htaccess set with ExpiresActive On is working though

I don't have this problem with css or text files properly setting expires header though.

Please check and make sure the MIME type is defined for javascript and png in LiteSpeed main MIME configuration file.
Try new 4.0.17 release.

those warnings are harmless.
Are you using LiteSpeed with hosting control panel? or configure everything in native configuration?
How the expires configuration being set?


Well-Known Member
Ah interesting it's working once i added apache mod_expires ??? more interesting is that the expire duration for most mime types is now taken from apache mod_expires overriding what is set in litespeed admin control panel. The exception being css mime type files now has expire duration of

which doesn't correspond to either apache mod_expires nor does it match litespeed set css type ? so where is being set to max-age=31536000 ?

disregard css issue, once set vb for css to saved as file in admincp, it picked up mod_expires set duration overriding litespeed values for css like other mime types.

So basically for expires to work for litespeed/whm/cpanel server, mod_expires for apache needs to be configured !

just browse a vB 4 source, looks like css.php did the trick. but no test.


Well-Known Member
ah yes css.php :)

so is this by design or a bug that apache mod_expires overrides litespeed values for expire types and that mod_expires needs to be set for litespeed to process png and css files for expire headers - only 2 mime types need for this requirement?


LiteSpeed Staff
It is by design, we want LiteSpeed behave exactly the same as Apache when load Apache httpd.conf.
However, enabling expires header by default regardless Apache configuration may not be bad idea either. it only helps. So, yeah, we may turn it on by default in next release. :)


and, if not read apache's httpd.conf, in lsws native configuration, Expires header is enabled by default for png/js/css/jpg.

I'd mark this thread as Resolved.
