OPTIMISING
|
|
|
|
|
==========
|
|
|
|
|
|
|
|
|
|
There are two forms of optimisation here, compression and caching, both aimed
|
|
|
|
|
at increasing an end user's experience using RoundCube Webmail. Compression
|
|
|
|
|
allows the static web pages to be delivered with less bandwidth. The index.php
|
|
|
|
|
of RoundCube Webmail already enables compression on its output. The settings
|
|
|
|
|
below allow compression to occur for all static files. Caching sets HTTP
|
|
|
|
|
response headers that enable a user's web client to understand what is static
|
|
|
|
|
and how to cache it.
|
|
|
|
|
|
|
|
|
|
The caching directives used are:
|
|
|
|
|
* Etags - sets at tag so the client can request is the page has changed
|
|
|
|
|
* Cache-control - defines the age of the page and that the page is 'public'
|
|
|
|
|
This enables clients to cache javascript files that don't have private
|
|
|
|
|
information between sessions even if using HTTPS. It also allows proxies
|
|
|
|
|
to share the same cached page between users.
|
|
|
|
|
* Expires - provides another hint to increase the lifetime of static pages.
|
|
|
|
|
|
|
|
|
|
For more information refer to RFC 2616.
|
|
|
|
|
|
|
|
|
|
Side effects:
|
|
|
|
|
-------------
|
|
|
|
|
These directives are designed for production use. If you are using this in
|
|
|
|
|
a development environment you may get horribly confused if your webclient
|
|
|
|
|
is caching stuff that you changed on the server. Disabling the expires
|
|
|
|
|
parts below should save you some grief.
|
|
|
|
|
|
|
|
|
|
If you are changing the skins, it is recommended that you copy content to
|
|
|
|
|
a different directory apart from 'default'.
|
|
|
|
|
|
|
|
|
|
Apache:
|
|
|
|
|
-------
|
|
|
|
|
To enable these features in apache the following modules need to be enabled:
|
|
|
|
|
* mod_compress
|
|
|
|
|
* mod_expire
|
|
|
|
|
* mod_headers
|
|
|
|
|
|
|
|
|
|
The optimisation is already included in the .htaccess file in the top
|
|
|
|
|
directory of your installation.
|
|
|
|
|
|
|
|
|
|
If you are using Apache version 2.2.9 and later, in the .htaccess file
|
|
|
|
|
change the 'append' word to 'merge' for a more correct response. Keeping
|
|
|
|
|
as 'append' shouldn't cause any problems though changing to merge will
|
|
|
|
|
eliminate the possibility of duplicate 'public' headers in Cache-control.
|
|
|
|
|
|
|
|
|
|
Lighttpd:
|
|
|
|
|
---------
|
|
|
|
|
With Lightty the addition of Expire: tags by mod_expire is incompatible with
|
|
|
|
|
the addition of "Cache-control: public". Using Cache-control 'public' is
|
|
|
|
|
used below as it is assumed to give a better caching result.
|
|
|
|
|
|
|
|
|
|
Enable modules in server.modules:
|
|
|
|
|
"mod_setenv"
|
|
|
|
|
"mod_compress"
|
|
|
|
|
|
|
|
|
|
Mod_compress is a server side cache of compressed files to improve its performance.
|
|
|
|
|
|
|
|
|
|
$HTTP["host"] == "www.example.com" {
|
|
|
|
|
|
|
|
|
|
static-file.etags = "enable"
|
|
|
|
|
# http://redmine.lighttpd.net/projects/lighttpd/wiki/Etag.use-mtimeDetails
|
|
|
|
|
etag.use-mtime = "enable"
|
|
|
|
|
|
|
|
|
|
# http://redmine.lighttpd.net/projects/lighttpd/wiki/Docs:ModSetEnv
|
|
|
|
|
$HTTP["url"] =~ "^/roundcubemail/(plugins|skins|program)" {
|
|
|
|
|
setenv.add-response-header = ( "Cache-Control" => "public, max-age=2592000")
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
# http://redmine.lighttpd.net/projects/lighttpd/wiki/Docs:ModCompress
|
|
|
|
|
# set compress.cache-dir to somewhere outside the docroot.
|
|
|
|
|
compress.cache-dir = var.statedir + "/cache/compress"
|
|
|
|
|
|
|
|
|
|
compress.filetype = ("text/plain", "text/html", "text/javascript", "text/css", "text/xml", "image/gif", "image/png")
|
|
|
|
|
}
