SSL redirection rule with regular expresion

Sure you can do that. Make sure this iRule is on your HTTP virtual and not your HTTPS virtual or else you'll get into a circular loop.

when HTTP_REQUEST {
  switch -glob [HTTP::uri] {
    "/*/morethings" {
      HTTP::redirect "https://[HTTP::host][HTTP::uri]"
    }
  }
}

This will match the following

http://www.foo.com/onething/morethings

http://www.foo.com/onething/twothing/morethings

...

It will not match this:

http://www.foo.com/morethings

Now, if you just want to make sure that your URI ends with "/morethings" you can do something simple like this:

when HTTP_REQUEST {
  if { [HTTP::uri] ends_with "/morethings" } {
    HTTP::redirect "https://[HTTP::host][HTTP::uri]"
  }
}

Hopefully this will get you going in the right direction.

Thanks Joe. But I want to redirect only if :

 

 

URI STARTS with /???/ where ? match 1 letter so if I have :

 

 

/abc/xxxxx --> match

 

/abcd/xxxx ---> doesn´t match

 

/pirulo --> doesn´t match

 

Just change the match pattern in the switch statement:

when HTTP_REQUEST {
  switch -glob [HTTP::uri] {
    "/abcd/*" -
    "/efgh/*" -
    "/ijkl/*" {
      HTTP::redirect "https://[HTTP::host][HTTP::uri]"
    }
  }
}

This will match only on the following

http://www.foo.com/abcd/*

http://www.foo.com/efgh/*

http://www.foo.com/ijkl/*

It will not match on

http://www.foo.com/aaaa/abcd/*

http://www.foo.com/abcd

http://www.foo.com/abc

http://www.foo.com/ab

That's because of the second slash in the match strings. Just modify the match statement using wildcards (*) for any sequence of characters/numbers/symbols/etc.

Joe, Sorry I think I´m not explaining my problem correct.

 

 

URI STARTS with /???/ where ? match 1 letter (Using regular expresions) so if I have for example :

 

 

/abc/xxxxx --> match so /[a-z][a-z][a-z]/

 

3 letters from a to z

 

 

/abcd/xxxx ---> doesn´t match

 

/pirulo --> doesn´t match

I think Joe is suggesting using the switch command with strings instead of a regex because it's more resource intensive to use a regex.

You can use the question mark as a wildcard representing any single character. So this should match what you've described so far, where any request that starts with /, any three characters, another forward slash followed by anything would be redirected to the same host and URI via HTTPS:

when HTTP_REQUEST {
  switch -glob [HTTP::uri] {
    /???/* {
      HTTP::redirect "https://[HTTP::host][HTTP::uri]"
    }
  }
}

You can check the TCL man page on switch (Click here) and string match (Click here) for details on string wildcards.
