One Vs for Redirects

Thanks guys! I think I'm close, can you show me the example with using the v9 datagroups?

 

 

Thanks!

Here is one on v9

I hope this helps

Hmm think I'm hitting a wall here. Do you think you can work that data group into what I'm trying to do?

 

 

much appreciated..

The solution Matt suggested was to create a datagroup containing the HTTP host names that the client would be making requests to. He then used string map to rewrite a static string from the requested hostname to a new value and send that new value in a redirect to the client.

Is that the basic function you're looking for? If so, have you been able to create the datagroup and iRule? Is the match found in the datagroup?

Can you try this version with logging added?

 
 when HTTP_REQUEST { 
  
     Log the request details and class contents.  Need to use $:: to reference the class name here. 
    log local0. "[IP::client_addr]:[TCP::client_port]: [HTTP::method] to [HTTP::host][HTTP::uri] with class: $::my_hosts_class" 
  
     Check if the requested host is in the my_hosts_class datagroup 
    if { [matchclass [HTTP::host] equals my_hosts_class] } { 
       log local0. "[IP::client_addr]:[TCP::client_port]: Matched!" 
       HTTP::redirect http://[string map -nocase {"www" "my"} [HTTP::host]][HTTP::uri] 
    } else { 
       HTTP::respond 200 content " Sorry, no match " 
       log local0. "[IP::client_addr]:[TCP::client_port]: No match" 
    } 
 } 
 

Make sure to update the iRule to use the name of the datagroup you've created. And I'd suggest not using a hyphen in the datagroup name as you'd then need to use curly braces to reference it.

Stll not working, this is the log output on it;

 

 

11:05:08 tmm tmm[1144]: Rule VSred : 24.103.209.82:1172: GET to www.my.domain.com/ with class: {www.my.domain.com my.domain.com}

 

Feb 25 11:05:08 tmm tmm[1144]: 01220001:3: TCL error: Rule VSred - Invalid matchclass operands - no class or list type found, lhs: string, rhs: my_hosts_class (line 1) invoked from within "matchclass [HTTP::host] equals my_hosts_class"

 

 

I created a String data group with one line, www.my.domain.com my.domain.com

 

 

 

Thanks for all the help guys!

 

Maybe the reference to the class with $:: in the log line is breaking the matchclass command? Can you remove this portion of the log line:

 

 

with class: $::my_hosts_class

 

 

and retest?

 

 

Thanks,

Thanks for the quick reply!

This is how the rule looks now.

 when HTTP_REQUEST {  
      Log the request details and class contents.  Need to use $:: to reference the class name here. 
 log local0. "[IP::client_addr]:[TCP::client_port]: [HTTP::method] to [HTTP::host][HTTP::uri]" 
  Check if the requested host is in the my_hosts_class datagroup 
 if { [matchclass [HTTP::host] equals my_hosts_class] } { 
 log local0. "[IP::client_addr]:[TCP::client_port]: Matched!" 
 HTTP::redirect http://[string map -nocase {"www" "my"} [HTTP::host]][HTTP::uri] 
 } else { 
 HTTP::respond 200 content " Sorry, no match " 
 log local0. "[IP::client_addr]:[TCP::client_port]: No match" 
 } 
 } 

log:

Sorry that time I tested it looked like I had the hostnames on seperate lines in the data group, they're back to being on one line, log looks the same...

You'll want each hostname on a separate line in the datagroup.

 

 

Are you still running 9.4.8? Is the literal name of the datagroup you've created my_hosts_class?

 

 

Can you post the anonymized output from:

 

 

b class my_hosts_class list

 

 

Thanks,

 

Aaron

Or maybe it's this known issue in 9.4.x?

 

 

 

iRule TCL class coerced to wrong type (CR87914)

 

If an iRule uses a TCL class as a command, the class is coerced into a TCL command name which renders is useless for any typical class use.

 

Using the class in a matchclass command, causes an error as the command expects a class variable. Errors such as Invalid command name or Invalid matchclass operands are then written to the /var/log/ltm file.

 

 

Example code:

 

class valid_methods {

 

"GET"

 

"HEAD"

 

"OPTIONS"

 

"POST"

 

}

 

 

rule error_rule {

 

when HTTP_REQUEST {

 

log local0. "Hello [$::valid_methods]"

 

 

}

 

}

 

 

 

 

Did you have square braces around the datagroup name at some point? If so, running 'b load' should fix this.
