NimbostratusiRule to modify the URI without a client redirect
You may want to look at this page:
https://devcentral.f5.com/wiki/iRules.HTTP__uri.ashx
Using a redirect will change the URL on the browser.
Changing the Host header only affects what the server gets.
You will need the IP address of la.mysite.com, say it is 1.2.3.4
You will need an irule like this:
when HTTP_REQUEST { if { [HTTP::uri] equals "/" } { the node command directs the request to the server whether or not it is behind the BigIP. Make sure the BigIP has a route to that server. node 1.2.3.4 In case you don't have SNAT on the virtual, you may need it here. snat automap In case the server complains, set the host header. HTTP::header replace Host "la.mysite.com" Finally change the URI while on its way to server. HTTP::uri /documents/china.pdf } }Here is the page for the SNAT command:

Here is the page for the node command:
NimbostratusLet me see if I have your plan correct:
- User connects to https://china.mysite.com/
- User gets redirected to https://china.mysite.com/documents/china.pdf
- User requests that URL, which causes the BIG-IP to send the request to a pool for the la.mysite.com server.
I think this might be what you want:
when HTTP_REQUEST {
if {[HTTP::host] equals "china.mysite.com"}{
if {[HTTP::uri] equals "/"}{
HTTP::redirect "/documents/china.pdf"
} elseif {[HTTP::uri] equals "/documents/china.pdf"}{
HTTP::host "la.mysite.com"
pool la_mysite_pool
}
}
}
What is does:
If the host equals china.mysite.com and the URI equals /, redirect to /documents/china.pdf. If the host equals china.mysite.com and the URI equals /documents/china.pdf, change the host header in the HTTP request to la.mysite.com and send the request to the pool that contains the server hosting la.mysite.com.
Make sense?
