Google Analytics

Hi,

 

 

Your product is a licensed LTM or something else like GTM/LC? if this is not a LTM you won't have those functionalities

 

 

To be able to use HTTP_REQUEST/HTTP_RESPONSE, you'll need to assign a HTTP profile to your vs but RULE_INIT should be accepted. The only reason for me if it doesn't work is that you have a LC.

 

 

If you have a LTM, can you show us the exact output you have when you try to save the iRule ?

Thanks for the reply. We have an LTM 1500

 

 

Here is the error when I try to save the iRule.

Hi,

 

 

We'll need your iRule to understand your error, can you try posting your code here within [ code ] [ / code ] ?

 

 

This way it should print correctly

 

 

Thanks

 

 

N.

Here's the code. The only parts I've added were the first two lines, and the last two close braces. So it's basically the Google Analytics script from here on Devcentral.

 

 

 

[ code ]

 

 

when HTTP_REQUEST {

 

if { [HTTP::host] eq "www.domain.com" } {

 

 

when RULE_INIT {

 

replace the value of the _uacct variable with your Google Analytics account.

 

set analytics "

 

 

 

"

 

 

set exist_search "urchinTracker()"

 

}

 

when HTTP_REQUEST {

 

Don't allow data to be chunked

 

if { [HTTP::version] eq "1.1" } {

 

if { [HTTP::header is_keepalive] } {

 

HTTP::header replace "Connection" "Keep-Alive"

 

}

 

HTTP::version "1.0"

 

}

 

}

 

when HTTP_RESPONSE {

 

if { [HTTP::header Content-Type] starts_with "text/html" } {

 

if { [HTTP::header exists "Content-Length"] } {

 

log local0. "content length: [HTTP::header {Content-Length}]"

 

set content_length [HTTP::header "Content-Length"]

 

} else {

 

set content_length 1000000000

 

}

 

log local0. "Collecting $content_length bytes"

 

if { $content_length > 0 } {

 

HTTP::collect $content_length

 

}

 

}

 

}

 

when HTTP_RESPONSE_DATA {

 

log local0. "Content Type: [HTTP::header Content-Type]"

 

if { ! ([HTTP::payload] contains $::exist_search) } {

 

log local0. "Payload didn't contain $::exist_search!"

 

set idx [string last "" [HTTP::payload]]

 

if { -1 == $idx } {

 

set idx [string last "" [HTTP::payload]]

 

}

 

log local0. "html end tag found at $idx"

 

if { -1 == $idx } {

 

set offset [HTTP::payload length]

 

} else {

 

set offset $idx

 

}

 

HTTP::payload replace $offset 0 $::analytics

 

}

 

}

 

 

}}

Can you remove all the space in your [] for code ? i did it simply so that you could see which mark to use

I'm not sure what you mean by removing the space. Is this OK now?

when HTTP_REQUEST { 
 if { [HTTP::host] eq "www.domain.com"} { 
 when RULE_INIT {   
  replace the value of the _uacct variable with your Google Analytics account.   
 set analytics " 
  
  
 " 
 set exist_search "urchinTracker()" 
 } 
 when HTTP_REQUEST {   
  Don't allow data to be chunked   
 if { [HTTP::version] eq "1.1" } {     
 if { [HTTP::header is_keepalive] } {       
 HTTP::header replace "Connection" "Keep-Alive" 
 }     
 HTTP::version "1.0"   
 } 
 } 
 when HTTP_RESPONSE {   
 if { [HTTP::header Content-Type] starts_with "text/html" } {     
 if { [HTTP::header exists "Content-Length"] } {       
 log local0. "content length: [HTTP::header {Content-Length}]"       
 set content_length [HTTP::header "Content-Length"]     
 } else {       
 set content_length 1000000000     
 }     
 log local0. "Collecting $content_length bytes"     
 if { $content_length > 0 } {        
 HTTP::collect $content_length     
 }   
 } 
 } 
 when HTTP_RESPONSE_DATA {   
 log local0. "Content Type: [HTTP::header Content-Type]"   
 if { ! ([HTTP::payload] contains $::exist_search) } {     
 log local0. "Payload didn't contain $::exist_search!"     
 set idx [string last "" [HTTP::payload]]     
 if { -1 == $idx } {       
 set idx [string last "" [HTTP::payload]] 
 }     
 log local0. "html end tag found at $idx"     
 if { -1 == $idx } {       
 set offset [HTTP::payload length]     
 } else {      
 set offset $idx    
 }     
 HTTP::payload replace $offset 0 $::analytics   
 } 
 } 
 }}

Hi,

 

 

Ok you did it wrong, you should try something like this instead

 

 

 
 when RULE_INIT { 
    replace the value of the _uacct variable with your Google Analytics account. 
   set analytics " 
  
  
  
 " 
   set exist_search "urchinTracker()" 
 } 
 when HTTP_REQUEST { 
   set activate_analytics 0 
   if {[HTTP::host] equals "www.domain.com"} { 
         Don't allow data to be chunked 
        if { [HTTP::version] eq "1.1" } { 
            if { [HTTP::header is_keepalive] } { 
               HTTP::header replace "Connection" "Keep-Alive" 
            } 
            HTTP::version "1.0" 
        } 
        set activate_analytics 1 
   } 
 } 
 when HTTP_RESPONSE { 
   if {$activate_analytics equals "1"} { 
        if { [HTTP::header Content-Type] starts_with "text/html" } { 
           if { [HTTP::header exists "Content-Length"] } { 
              log local0. "content length: [HTTP::header {Content-Length}]" 
              set content_length [HTTP::header "Content-Length"] 
           } else { 
           set content_length 1000000000 
         } 
         log local0. "Collecting $content_length bytes" 
         if { $content_length > 0 } { 
            HTTP::collect $content_length 
         } 
       } 
    } 
 } 
 when HTTP_RESPONSE_DATA { 
   log local0. "Content Type: [HTTP::header Content-Type]" 
   if { ! ([HTTP::payload] contains $::exist_search) } { 
     log local0. "Payload didn't contain $::exist_search!" 
     set idx [string last "" [HTTP::payload]] 
     if { -1 == $idx } { 
       set idx [string last "" [HTTP::payload]] 
     } 
     log local0. "html end tag found at $idx" 
     if { -1 == $idx } { 
       set offset [HTTP::payload length] 
     } else { 
       set offset $idx 
     } 
     HTTP::payload replace $offset 0 $::analytics 
   } 
 } 
 

 

 

Here with the variable activate_analytics we will trigger the code only if the domain matched

Thanks for your very prompt response. I'll give that a go.

 

 

Cheers!
