NimbostratusAdd google analytics code to payload
Hi all,
I want to add the google analytics code to payload by irules and I have created the following ..
when HTTP_RESPONSE {
set clen [HTTP::header Content-Length]
HTTP::collect $clen
}
when HTTP_REQUEST_DATA {
set google_code " "
regsub -all "" [HTTP::payload] $google_code new_payload
HTTP::payload replace 0 $clen $new_payload
}
but it seems not working, does any one has any idea about that ? thank you in advance ..

Hi Ken,
That's a good start. You could take the second example on the HTTP::collect wiki page (Click here and add a check to see that the response content type contains "text" (or other relevant content-types for you):if {[HTTP::header "Content-Length"] contains "text" && \ [HTTP::header exists "Content-Length"] && [HTTP::header "Content-Length"] <= 1048576}{
In HTTP_REQUEST_DATA, you could then insert the Google Javascript using:
HTTP::payload replace 0 0 $new_payload
The first digit is the offset. 0 starts the insertion at the beginning. The second digit is the length of the string to replace. 0 replaces nothing.
Aaron- The_BhattmanHi Ken,
Not sure if saw this but here is excellent article regarding adding Google analytics to an existing page.

I hope this helps
Bhattman - Madiw_114772Just for people that would need that in the future, I used HTTP_RESPONSE_DATA instead of HTTP_REQUEST_DATA For the testing on the content, I used if {[HTTP::header "Content-Type"] contains "text" && [HTTP::header exists "Content-Length"] && [HTTP::header "Content-Length"] <= 1048576}{
