Redirecting HTTP to a website using iRule

Do you need something more than the following:

       
     b rule myredir show     
     RULE myredir {     
        if (http_host == "www.company.com") {     
           redirect to "http://www.company.com:5000/dir"     
        }     
        else {     
           discard     
        }     
     } 
  

Sorry about the confusion, the initial command was the output of a rule show.

 
  
 b rule myredir '{if(http_host == "x.xx.xxx") { redirect to "http://x.xx.xxx:80/index.shtml" }' 
  
 b virtual 192.168.1.22:0 { use rule myredir } 
  
 

From a box on the .1 network:

 
 bash-2.05b$ telnet 192.168.1.22 6666    it could be any port 
 Trying 192.168.1.22... 
 Connected to 192.168.1.22. 
 Escape character is '^]'. 
 GET / HTTP/1.0 
 Host:  x.xx.xxx 
 HTTP/1.0 302 Found 
 Location: http://x.xx.xxx:80/index.shtml 
 Connection: close 
  
 Connection closed by foreign host. 
 bash-2.05b$  
 

Finally, it's important to understand that a 4.X rule allows a limited number of branches so if you intend to do a lot of comparisons, you'll want to do something different. I don't have anything specific, but I'd guess a rule and class combination* will give you what you want.

*ask.f5.com probably has a good example of mapclass2node usage. I suspect the solutions guide does as well.

When I insert the below syntax into the Rule text section in the Configuration Utility I recieve an error:

 

 

b rule myredir '{if(http_host == "x.xx.xxx") { redirect to "http://x.xx.xxx:80/index.shtml" }' b virtual 192.168.1.22:0 { use rule myredir }

 

 

Error 331835 -- Rule string to tree failed. - syntax error at '''

 

line 1: if (http_host == "xx.xxxx.com") { redirect to "http://xx.xxxx.com:50000/xxx" }'

 

 

I also tried to use the syntax in the BIGPIPE command line section, I also received an error.

 

 

I do see from your last post that the website was redirected. I must still be implementing it incorrectly. Are you sure that this will work with version 4.6.2 on BIGIP 540?

 

 

More suggestions?

 

 

Thank you for your patience...

I've included my shell interaction below:

 
 knotwell:~ b rule myredir1 '{ if(http_host == "x.xx.xxx") { redirect to "http://xxx.xxx:80000/dir" }}' 
 knotwell:~ b virtual 192.168.1.222:0 { use rule myredir1 } 
 knotwell:~  
 

There are two separate commands and the virtual command must be issued *after* the rule command since a rule may not be used prior to its definition. Furthermore, the rule body must be quoted properly.

I just tried out this rule on 4.6.2 and it loaded properly.

 if (http_host == "www.company.com") { 
    redirect to "http://www.company.com:5000/dir" 
  } 
  else { 
    discard 
  }

Also, the following command line version should work:

bigpipe rule myredir '{if (http_host == "www.mycompany.com") { redirect to "http://www.company.com:5000/dir" }}'

Assumption: www.company.com resolves to the unused ip you've chosen and the resolution to it has a vip as well.

 

 

If you test the request by hand like I did earlier using telnet, it should be relatively easy to see what's happening.

I got it working. Thank you for your help!

 

 

Besides the syntax for the redirect I needed 2 VIPS. One connected to the rule for the redirect, then a second to the load balancing pool.

 

 

Have a great day!
