NimbostratusBlock Irule
Hi Guys,
i have written an irule in order to block some specific user agents
when HTTP_REQUEST {
if {[class match [string tolower [HTTP::header "User-Agent"]] contains Blocked_Users]}{
log local0. "Request from ip: [IP::client_addr] - User-Agent: [HTTP::header User-Agent] to: [HTTP::host] [HTTP::uri]"
drop
}
}
and i get logs like this:
TCL error: /Common/<http_request> - Can't call after responding - ERR_NOT_SUPPORTED (line 1) invoked from within "HTTP::header "User-Agent""</http_request></131>
I would like to know what does this mean more precisily , if the traffic is passing anyway even if its part of the blocked DG, does irule has any error or something .
Many thnx,
Daniel

Thanks for being part of our community. Hello,
Are you assinging another irules on the same virtual server? Also, can you share how did you create the data group?
There is a post mentioning the a similar error which is:
"Can't call after responding - ERR_NOT_SUPPORTED (line 1) invoked from within"
Thanks,
