Cirrostratus
CirrostratusRedirect IRULE
Looking for a bit of help please guys...
I am trying to write an IRULE that rewrites the host and uri but without doing a re-direct to clients browser.
when HTTP_REQUEST
if {[HTTP::host] equals "www.company.com" && [HTTP::uri] equals "/application"} {
HTTP::header replace Host "www.newcompany.com"
HTTP::uri /full/application/is/here
virtual VS_THIS_IS_WHERE_NEW_COMPANY_IS_CONFIGURED
}
}
The new virtual server where traffic is getting routed to does have client & server SSL profiles configured.
Both virtual servers (for old & new company) work fine.
I think I am missing something obvious but just can't see it.....
Thanks in advance for your help!

i think you have to use pool command (to new company pool) instead of virtual command.
LyonsG_85618Nitass....thanks for reply. I have tried pool command too.
Doing some further testing I have managed to get the syntax working on an internal BIG-IP.
The rules above is defined on BIG-IP's behind firewalls. I am now thinking (perhaps)
the firewall rules are not set correctly?- nitassthe firewall rules are not set correctly?i do not think so. i understand virtual command will send traffic to VS_THIS_IS_WHERE_NEW_COMPANY_IS_CONFIGURED internally (within bigip). so, firewall should not matter.
what i think is host header and uri might not be changed when sending to VS_THIS_IS_WHERE_NEW_COMPANY_IS_CONFIGURED. - nitasssorry i am wrong.

what exactly is the issue now? i don't see what fails ...
how you tried with tcpdump to see where to traffic goes?- LyonsG_85618
Thanks for help.
Looks like the problem was that there was another IRULE on the virutal server.
I added "event disable all" to end of this IRULE and traffic is now hitting the other virtual server.
Many thanks
