+Redirector is an extension for Firefox that allows you to automatically redirect from + one webpage to another. For example, every time you visit http://abc.com you will automatically + load http://def.com instead. This can be useful for instance to always redirect articles to printer friendly + versions, redirect http:// to https:// for sites that support both, bypass advertising pages that appear before + being able to view certain pages and more.
+ + +To add a new redirect you can go to the Tools menuitem and select Redirector. That will + open the Redirector settings window which shows all your redirects. The window can also be opened + by right clicking on the R icon in your statusbar. + There you can press the Add... button and then you can enter the details for the new redirect. A redirect + consists of a few things: +
Wildcards are the simplest way to specify include and exclude patterns. When you create a wildcard pattern there + is just one special character, the asterisk *. An asterisk in your pattern will match zero or more characters and you can + have more than one star in your pattern. Some examples: +
Regular expressions allow for more complicated patterns but they are a lot harder to learn than wildcards. I'm not gonna + create a regex tutorial here but normal javascript regex syntax works, look at http://regular-expressions.info for + an introduction to regular expressions. $1,$2 etc. can be used in the redirect url and will be replaced with contents of captures in + the regular expressions. Captures are specified with parantheses. Example: http://example.com/index.asp\?id=(\d+) will match the url + http://example.com/index.asp?id=12345 and $1 will be replaced by 12345. (A common mistake in regex patterns is to forget to escape + the ? sign in the querystring of the url. ? is a special character in regular expressions so if you want to match an url with a querystring + you should escape it as \?).
