NimbostratusLog length of css file in response
Hi,
I have a problem in the following case:
On a website there is a css-file that sometimes is not completely transferred to the client in the response. Now I like to write an iRule, that logs the length of this file when it is transferred to the client in server response, but I do not really know how to get _only_ information about this file in HTTP_RESPONSE event.
The request is a GET for /a/b/main.css
Regards,
Sören

You can set a variable on the request, only when you see this URL and then you should be able to read the value of the HTTP Content-Length header in any response, only if the variable has been set. Does that make sense?

ssievers_87378Hi,
yes - I know. I wrote an iRule in my first try like this:
when HTTP_REQUEST {
if { [HTTP::uri] eq "/a/b/main.css" }
log local0. "CSS-DEBUG: [HTTP::uri]"
}
}
when HTTP_RESPONSE {
if { [HTTP::header "Content-type"] eq "text/css" }{
log local0. "CSS-DEBUG: Content-Length is [HTTP::header Content-Length]"
}
}
The log shows me now all Content-Length values for all css-Files delivered to the clients (there is more than one css-File on the site). How can I only log the contend length from the main.css ?- nitass

can you try something like this?when HTTP_REQUEST { set uri [HTTP::uri] } when HTTP_RESPONSE { if { $uri equals "/a/b/main.css" } { log local0. "CSS-DEBUG: Content-Length is [HTTP::header Content-Length]" } } - ssievers_87378
Hi,
thanks - It works. I never thought that it can be so easy :-)

hoolioA tweak to avoid saving the URI for every request:when HTTP_REQUEST { if { [HTTP::uri] equals "/a/b/main.css" } { set log_cl 1 } else { set log_cl 0 } } when HTTP_RESPONSE { if {$log_cl}{ log local0. "CSS-DEBUG: Content-Length is [HTTP::header Content-Length]" } }
