Internal class format

On 10.1 this is what works for me:

 
 class foo { 
    {  
          "www.one.com www.foo.com" 
          "www.two.com www.bar.com" 
     } 
 }

This format works in v10.0.1 as well. But does it make the entry as name/value pairs so it it easy to lookup value based on the key?

I just tested it. It doesn't. The whole line is treat as the name of the element. I have to parse it.

It sounds like the below format should be valid for internal calls in v10.0.1, according to the class wiki page. I wonder why it couldn't pass the verify command

 
 class namevalue { 
    { 
       "name1" { "value" } 
       "name2" { "value" } 
    } 
 } 
 

Any help is appeciated!

Well the format

 
 class keyvalue { 
    { 
       "onekey" { "onevalue" } 
       "twokey" { "twovalue" } 
    } 
 } 
 

is the way that the GUI adds in the key/value pairs when you create the DG via the GUI itself. That verifies on my vLTM. I don't see why it wouldn't validate on yours. Are you sure the error is in the class itself and not before it?

I used GUI, created a string datagroup, added these two string entries:

 
 "name1" {"value1"} 
 "name2" {"value2"} 
 

After save, open config file and they are saved as:

 
 class namevalues{ 
    { 
       "\"name1\" {\"value1\"}" 
       "\"name2\" {\"value2\"}" 
    } 
 } 
 

Each line is treated as the name of element. so [class names namevalues] command returns:

 
 {"name1" {"value1"}} {"name2" {"value2"}} 
 

[class match -value "name1" equals namevalues] returns nothing.

This rule works with the original format I posted above. The idea of the rule is to redirect based on a lookup of the original HTTP::host header value. For example,

 

with a class like:

 

class foo {

 

{

 

"www.one.com www.foo.com"

 

"www.two.com www.bar.com"

 

}

 

}

 

The following code:

 

 
 when HTTP_REQUEST {   
      set Host [findclass [HTTP::host] dc-post " "] 
 log local0. "Host var is $Host"  
      if { $Host ne "" } {  
           HTTP::redirect http://$Host[HTTP::uri]  
           }  
   } 
 

 

...will lookup the k/v pair where www.one.com or www.two.com are the keys, and redirect to the value (www.foo.com or www.bar.com).

 

It may be of value to have a look at this post: https://devcentral.f5.com/Default.aspx?tabid=53&view=topic&postid=1144951&forumid=5&tpage=1

I think qqdixf5 is using 10.0.x which might handle class -name and class -value differently than 10.1.x. I think in order to use class -name/-value in 10.0.x, you'd need to use the := format in an external datagroup.
