Setting "Vary: Accept-Encoding" header using .htaccess

[aavmurphy]

In .htaccess file, I have:

Header set Vary Accept-Encoding

(as recommended by google chrome - options - javascript console - pagespeed)

But 2 "vary" headers are returned ("set" should set the header, not add a new one)

I've tried 'unset Header', but that doesnt work either

5.0 should follow "Header set ..." behavior. for 4.2.x, all header operations works as "Header append ...".

current litespeed version is 4.2.2

tried
Header append

but stil get 2 headers

according to the apache doco
AddOutputFilterByType DEFLATE text/html text/plain text/xml application/javascript text/css

sets the "Vary: User-Agent" header

i want to replace than with "Vary: Accept-Encoding"

i've tried
header set,
header unset, folowed by header set
header append

but none seem to work

Upgrade to 5.0 with command

/usr/local/lsws/admin/misc/lsup.sh -f -v 5.0

How to know cache hit or miss? How to enabled that tag?

How to enabled that tag?

Cache header will automatically be set if LSCache is used. No Cache - No Header - No Header - No Cache. You need either a cache plugin or at least .htaccess rewrite rules to enable LSCache.
