Rewrite rule not working, what am I missing?

Hi Bob,

Your last check is on the HTTP::host value, but you're looking for a host and URI.

You can use switch to do this a little cleaner and more efficiently:

 
 when HTTP_REQUEST { 
    switch "[string tolower [HTTP::host]]" { 
       "domain1.com" - 
       "www.domain1.com" { 
          HTTP::respond 301 Location "http://domain2.com 
       } 
       "domain3.com" - 
       "www.domain3.com" { 
          HTTP::respond 301 Location "https://domain3-edit.com 
       } 
       "www.domain4.com" { 
          HTTP::respond 301 Location "http://domain4.com/" 
       } 
       "domain5.com" { 
          HTTP::respond 301 Location "https://domain5-edit.com/" 
       } 
       "www.domain6.com" { 
          HTTP::respond 301 Location "http://domain6.com/" 
       } 
       "www.domain7.com" { 
          HTTP::respond 301 Location "http://domain7.com/" 
       } 
       "domain7.com" { 
          if {[string tolower [HTTP::uri]] eq "/security"}{ 
             HTTP::respond 301 Location "http://domain7.com/"ciso/pages/services.aspx 
          } 
       } 
    } 
 }

Aaron...Thanks for the quick response and that is much cleaner then what I've been doing. It worked like a charm. I'm going to be looking at some other iRules I got and see about cleaning them up as well. This way seems much easier to maintain..

 

 

BTW..I've not seen that switch function before, where can I find more information on that?

 

 

Thanks again..

 

Bob

I forgot to ask, and I'm sure I can do this a couple of ways but since were being so clean I'd like to keep it that way.

 

 

The domain7 that I was looking to match both host and uri, I have other uri's on that same host that I have to redirect. Do I create a whole new entry, basically the same thing you gave me before or do I use an elseif in there, or is there a way to stack them like you did with the first entry using a "-"?

 

 

 

Thanks

 

Bob

 

 

 

when HTTP_REQUEST {

 

switch "[string tolower [HTTP::host]]" {

 

"domain1.com" -

 

"www.domain1.com" {

 

HTTP::respond 301 Location "http://domain2.com

 

}

 

"domain3.com" -

 

"www.domain3.com" {

 

HTTP::respond 301 Location "https://domain3-edit.com

 

}

 

"www.domain4.com" {

 

HTTP::respond 301 Location "http://domain4.com/"

 

}

 

"domain5.com" {

 

HTTP::respond 301 Location "https://domain5-edit.com/"

 

}

 

"www.domain6.com" {

 

HTTP::respond 301 Location "http://domain6.com/"

 

}

 

"www.domain7.com" {

Here is a set of TCL man pages for the 8.4 version of TCL current iRules are based on:

http://www.tcl.tk/man/tcl8.4/TclCmd/contents.htm

And here is the man page for switch:

http://www.tcl.tk/man/tcl8.4/TclCmd/switch.htm

If I understand correctly, you can use a nested switch statement for domain7.com URI checking:

    
  when HTTP_REQUEST {  
     switch "[string tolower [HTTP::host]]" {  
        "domain1.com" -  
        "www.domain1.com" {  
           HTTP::respond 301 Location "http://domain2.com  
        }  
        "domain3.com" -  
        "www.domain3.com" {  
           HTTP::respond 301 Location "https://domain3-edit.com  
        }  
        "www.domain4.com" {  
           HTTP::respond 301 Location "http://domain4.com/"  
        }  
        "domain5.com" {  
           HTTP::respond 301 Location "https://domain5-edit.com/"  
        }  
        "www.domain6.com" {  
           HTTP::respond 301 Location "http://domain6.com/"  
        }  
        "www.domain7.com" {  
           HTTP::respond 301 Location "http://domain7.com/"  
        }  
        "domain7.com" {  
           switch -glob "[string tolower [HTTP::uri]]" {  
       "/security" {  
       "/security/" -  
                  Exact match for "/security" or "/security/"  
                 HTTP::respond 301 Location "http://domain7.com/ciso/pages/services.aspx"  
              }  
       "/urib*" {  
                  URI starts with "/urib"  
                 HTTP::respond 301 Location "http://domain7.com/ciso/pages/urib.aspx"  
              }  
       "*uric" {  
                  URI ends with "uric"  
                 HTTP::respond 301 Location "http://domain7.com/ciso/pages/uric.aspx"  
              }  
       "*uri[d-f]" {  
                  URI ends with "urid", "urie" or "urif"  
                 HTTP::respond 301 Location "http://domain7.com/ciso/pages/uric.aspx"  
              }  
       "*uri?" {  
                  URI ends with "uri" and any other character (which hasn't already been matched like b, c, d-f)  
                 HTTP::respond 301 Location "http://domain7.com/ciso/pages/uric.aspx"  
              }  
           }  
        }  
        "www.domain8.com" {  
           HTTP::respond 301 Location "http://domain8.com/"  
        }  
        default {  
            Take some default action? 
        }  
     }  
  }  
    
    

Note the -glob flag on the URI checking. This allows you to use string patterns in the switch cases as defined in the 'string match' man page:

http://www.tcl.tk/man/tcl8.4/TclCmd/string.htmM35

string match ?-nocase? pattern string

See if pattern matches string; return 1 if it does, 0 if it doesn't. If -nocase is specified, then the pattern attempts to match against the string in a case insensitive manner. For the two strings to match, their contents must be identical except that the following special sequences may appear in pattern:

*

Matches any sequence of characters in string, including a null string.

?

Matches any single character in string.

[chars]

Matches any character in the set given by chars. If a sequence of the form x-y appears in chars, then any character between x and y, inclusive, will match. When used with -nocase, the end points of the range are converted to lower case first. Whereas {[A-z]} matches '_' when matching case-sensitively ('_' falls between the 'Z' and 'a'), with -nocase this is considered like {[A-Za-z]} (and probably what was meant in the first place).

\x

Matches the single character x. This provides a way of avoiding the special interpretation of the characters *?[]\ in pattern.

Wow..sweet, I did actually get it to work using elseif statements, but I like how you've done this. The only question I have is how do you break out of the -glob flag. Is it as simple as what I did when I added domain8.com at the bottom, or should I adding those type of domains before the -glob flag?

 

 

 

when HTTP_REQUEST {

 

switch "[string tolower [HTTP::host]]" {

 

"domain1.com" -

 

"www.domain1.com" {

 

HTTP::respond 301 Location "http://domain2.com

 

}

 

"domain3.com" -

 

"www.domain3.com" {

 

HTTP::respond 301 Location "https://domain3-edit.com

 

}

 

"www.domain4.com" {

 

HTTP::respond 301 Location "http://domain4.com/"

 

}

 

"domain5.com" {

 

HTTP::respond 301 Location "https://domain5-edit.com/"

 

}

 

"www.domain6.com" {

 

HTTP::respond 301 Location "http://domain6.com/"

 

}

 

"www.domain7.com" {

 

HTTP::respond 301 Location "http://domain7.com/"

 

}

 

"domain7.com" {

 

switch -glob "[string tolower [HTTP::uri]]" {

 

"/security" {

 

"/security/" -

 

Exact match for "/security" or "/security/"

 

HTTP::respond 301 Location "http://domain7.com/ciso/pages/services.aspx"

 

}

 

"/urib*" {

 

URI starts with "/urib"

 

HTTP::respond 301 Location "http://domain7.com/ciso/pages/urib.aspx"

 

}

 

"*uric" {

 

URI ends with "uric"

 

HTTP::respond 301 Location "http://domain7.com/ciso/pages/uric.aspx"

 

}

 

"*uri[d-f]" {

 

URI ends with "urid", "urie" or "urif"

 

HTTP::respond 301 Location "http://domain7.com/ciso/pages/uric.aspx"

 

}

 

"*uri?" {

 

URI ends with "uri" and any other character (which hasn't already been matched like b, c, d-f)

 

HTTP::respond 301 Location "http://domain7.com/ciso/pages/uric.aspx"

 

}

 

"www.domain8.com" {

 

HTTP::respond 301 Location "http://domain8.com/"

 

}

 

 

}

 

}

 

}

 

}

 

 

Thanks again this his very helpful...

 

 

Bob

Not sure how you get the rule in there with all the formatting in place but I can't seem to figure that one out..sorry it so flat, I'm sure that doesn't make it any easier for you to read...

 

 

Bob

I added a domain8 and a default case to the post above.

 

 

You can use [ code ] [ / code ] tags without the spaces to preserve formatting and prevent emoticons.

 

 

Aaron

Hey bob, check out the iRules wiki on "switch" I found it to be a little more reader friendly as they apply situations to the F5...

 

 

http://devcentral.f5.com/Default.aspx?tabid=63&articleType=ArticleView&articleId=129

 

 

Read up on all the wikis while you're at it... lots of info in there man..

Thanks a lot for the help on this, I really appreciate it!

 

 

Bob
