| | | an example how you can setup the sqlite.db for roundcube: |
|---|
| | | |
|---|
| | | # sqlite -init SQL/sqlite.initial.sql sqlite.db |
|---|
| | | Loading resources from SQL/sqlite.initial.sql |
|---|
| | | SQLite version 2.8.16 |
|---|
| | | Enter ".help" for instructions |
|---|
| | | sqlite> .exit |
|---|
| | | # chmod o+rw sqlite.db |
|---|
| | | |
|---|
| | | Make sure your configuration points to the sqlite.db file and that the |
|---|
| | | webserver can write to the file and the directory containing the file. |

| | | 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_deflate |
|---|
| | | * mod_expires |
|---|
| | | * 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") |
|---|
| | | } |
|---|
| | | |
|---|
| | | |
