Cirrusregex HTTP::header replace "Host"
I am trying to create an irule that can use a regex like:
/^([\s\S]?)(domain.com)./g
So if a user types:
domainname.com
abc.domainname.com
abc.domainname.com\xyz
It will still work.
Current irule
when HTTP_REQUEST {
if { [string tolower [HTTP::uri] ] contains "/?node=1" } {
HTTP::header replace "Host" "dev.domainname.com"
HTTP::path "/"
node 192.168.70.57 443
}
}
I have tried to put the irule in line but it keeps giving errors and google is no help at all.
when HTTP_REQUEST {
if { [string tolower [HTTP::uri] ] contains "/?node=1" } {
HTTP::header replace "Host" "/^([\s\S]*?)(domainname).*/g"
HTTP::path "/"
node 192.168.70.57 443
}
}

Anthony_FornitoI do not see an edit button but the irule would look like.
when HTTP_REQUEST { if { [string tolower [HTTP::uri] ] contains "/?node=1" } { HTTP::header replace "Host" "/^([\s\S]*?)(domainname.com).*(node=1)/g" HTTP::path "/" node 192.168.70.57 443 } }- Stanislas_Piro2

Anthony,
you created 2 threads about the same need.
in the previous thread, you wanted to balance based on a different hostname, which is the recommended solution. but at the end, you changed to load balancing based on a query string....
the issue is with this solution, only the first request will be sent to the good pool. next requests won't have this query string.I recommend you to explain the expected application behavior and not ask for an irule.
After, we can help you to choose the best solution.
