NimbostratusSimple Reverse Proxy with iRules
Hello!
I simply want to create a reverse proxy for http://mediawiki.pva.sozvers.at/.
I created a Virtual Server http://f5wiki.pva.sozvers.at/ , enabled the http-profile, the stream Profile, configured a default-pool with the node http://mediawiki.pva.sozvers.at/ and finally wrote an iRule. I worked everything through at this site https://techdocs.f5.com/content/kb/en-us/products/big-ip_ltm/manuals/product/ltm-implementations-11-6-0/25.html But I want to do that with iRules instead of the Rewrite Profile+Policy, as I am new to f5 and would like to learn more about it. So here is my Try:
when HTTP_REQUEST {
STREAM::disable
if { [HTTP::host] eq "f5wiki.pva.sozvers.at"} {
HTTP::redirect "http://mediawiki.pva.sozvers.at"
}
}
when HTTP_RESPONSE {
STREAM::disable
# Rewrite the Host header for redirects
HTTP::header replace "http://mediawiki.pva.sozvers.at" "f5wiki.pva.sozvers.at"
STREAM::enable
}
It almost works. When calling the f5wiki.pva.sozvers.at-host i get redirected to my Node wiki.
Problem is:, the URL changes to mediawiki..., where I want the URL to stay the same.
Can someone help me? Thank you
Hi, I know u said u want to make this using iRule - but I recommend you do it with policies. L7 policies use much less CPU than iRules and are easier to administer.
You create a virtual server and add a tcp and http profile - no other profiles needed. than you create a new pool with the node you need. than you create a new policy and in there, create a new rule with the conditions:
When:
"http host is any of f5wiki.pva.sozvers.at at request
Then:
Replace http host with value "mediawiki.pva.sozvers.at" at request
Forward traffic to pool "your pool" at request
Your failure with the iRule is the "http::redirect" . this sends a response to the client with the redirect to the new DNS name. this is wrong. If u want to do this with iRule:
when HTTP_REQUEST {
if { [HTTP::host] eq "f5wiki.pva.sozvers.at"} {
HTTP::header replace "f5wiki.pva.sozvers.at" "mediawiki.pva.sozvers.at"
pool /Common/yourpoolname
}
