Dynamic URLs

Sometimes you may want a target URL to contain information that can only be determined at the time of the redirect. For example, the client’s username.

Redirection allows you to use shortcodes in a redirect’s target URL. The most basic shortcodes allow data to be inserted:

  • [userid] – the client’s user ID, if logged in, or 0 if not logged in
  • [userlogin] – the client’s user login (login name), if logged in, or nothing if not logged in
  • [unixtime] – the current time, in Unix time format

For example:


Some shortcodes can contain data, and this data will be transformed. You would typically use this in a regular expression to transform some captured data.

The following transform shortcodes are supported:

  • [md5]data[/md5] – convert the data to the MD5 of the data
  • [upper]data[/upper] – uppercase the data
  • [lower]data[/lower] – lowercase the data
  • [dashes]data[/dashes] – convert any underscores in the data to dashes
  • [underscores]data[/underscores] – convert any dashes in the data to underscores

For example, your old site might use underscores to seperate words and you want to convert this to dashes:

Source: /oldsite/(.*)

Target: /newsite/[dashes]$1[/dashes]
