How can I Change IP Address references to FQDN references
Hi Guys
I am trying to use the STREAM command to replace the IP Address of the Virtual Server, with a FQDN (and vice versa)
I have Enabled streams on the Virtual server, and well as enabled Chunking on the both Request and Response.
============================
Rewrite the headers and links when you have to used IP addresses
as apposed to FQDN names in referencing the Virtual server.
when HTTP_REQUEST {
Check if response type is text
if {[HTTP::header value Content-Type] contains "text"}{
Enable the stream filter for the life of the current TCP connection
STREAM::enable
STREAM::expression {@}
}
}
when HTTP_RESPONSE {
Check if response type is text
if {[HTTP::header value Content-Type] contains "text"}{
Enable the stream filter for the life of the current TCP connection
STREAM::enable
STREAM::expression @}
}
}
I have checked the tcpdump (to the pool member) and the Host, and Referer and Location headers dont seem to be changing
Any ideas
Thnaks

Hi Gary,
When you add the stream profile to a virtual server with an HTTP profile, the rewriting only applies to the HTTP request and response payloads. You can selectively enable the stream profile from an iRule using STREAM::enable|disable. To rewrite HTTP request or response headers, you can use 'HTTP::header replace $header $new_value'.
Make sure to enable the stream filter after you set the stream expression:
STREAM::expression {@mysite.lab.com@172.16.20.34@}
STREAM::enable
For full feature HTTP proxying, check the ProxyPass iRule:
