There is mod_setenv for adding:
setenv.add-response-header = ( "Header" => "value" )
But I can't find anything to remove response headers.
I have to be sure, that my content is not cached by mobile operator proxies. On Apache I was doing it with:
<Directory "/path/to/dir">
Header set Cache-Control "no-cache, must-revalidate"
Header add Pragma "no-cache"
Header unset Last-Modified
RequestHeader unset If-Modified-Since
</Directory>
How can I do that in lighttpd?
This won't necessarily remove the Last-Modified header, but the end result may be similar to what you are looking for:
I hope this helps.
