NAME Catalyst::Plugin::VersionedURI - add version component to uris VERSION version 0.1.0 SYNOPSIS In your config file: uri static/ In "MyApp.pm": package MyApp; use Catalyst qw/ VersionedURI /; DESCRIPTION "Catalyst::Plugin::VersionedURI" adds a versioned component to uris matching a given set of regular expressions provided in the configuration file. In other word, it'll -- for example -- convert /static/images/foo.png into /static/v1.2.3/images/foo.png This can be useful, mainly, to have the static files of a site magically point to a new location upon new releases of the application, and thus bypass previously set expiration times. The versioned component of the uri resolves to "v"*$MyApp::VERSION*. CONFIGURATION uri The plugin's accepts any number of "uri" configuration elements, which are taken as regular expressions to be matched against the uris. The regular expressions are implicitly anchored at the beginning of the uri, and at the end by a '/'. WEB SERVER-SIDE CONFIGURATION Of course, the redirection to a versioned uri is a sham to fool the browsers into refreshing their cache. Usually we configure the front-facing web server to point back to the same directory. Apache Typically, the configuration on the Apache side used in conjecture with this plugin will look like: RewriteEngine on RewriteRule ^v[0123456789._]+/(.*)$ /myapp/static/$1 [PT] ExpiresActive on ExpiresDefault "access plus 1 year" YOU BROKE MY DEVELOPMENT SERVER, YOU INSENSITIVE CLOD! While the plugin is working fine with a web-server front-end, it's going to seriously cramp your style if you use, for example, the application's standalone server, as now all the newly-versioned uris are not going to resolve to anything. The obvious solution is, well, fairly obvious: remove the VersionedURI configuration stanza from your development configuration file. If, for whatever reason, you absolutly want your application to deal with the versioned paths with or without the web server front-end, you can use Catalyst::Controller::VersionedURI, which will undo what "Catalyst::Plugin::VersionedURI" toiled to shoe-horn in.
