iRule, Traffic Policy or Re-Write Policy

Hi sjy2025​ 

the best solution would be to config application use relative paths

for now you can try this irule, you will need to apply stream profile also

when CLIENT_ACCEPTED 
{
    STREAM::disable
    if {[class match [IP::client_addr] equals clients1] } 
    {
        pool POOL_1
    } 
    elseif {[class match [IP::client_addr] equals clients2] } 
    {
        pool POOL_2
    } elseif {[class match [IP::client_addr] equals clients3] }
    {
        pool POOL_3
    } elseif {[class match [IP::client_addr] equals clients4] } 
    {
        pool POOL_4
    } elseif {[class match [IP::client_addr] equals clients5] } 
    {
        pool POOL_5
    }
    else {
        pool POOL_6
    }
}


when HTTP_REQUEST 
{
    STREAM::disable
    HTTP::header remove "Accept-Encoding"
    set original_uri [HTTP::uri]
    HTTP::uri "/test${original_uri}"
}

when HTTP_RESPONSE 
{
    STREAM::disable
    if {[HTTP::header exists "Location"]} 
    {
        set loc [HTTP::header "Location"]
        if {[string match "https://examples.com*" $loc]} 
        {
            HTTP::header replace "Location" [string map {"https://examples.com" "https://example.com"} $loc]
        }
    }
    if {[HTTP::header "Content-Type"] contains "text"} 
    {
        STREAM::expression {@https://examples.com@https://example.com@}
        STREAM::enable
    }
}

Thank you for the irule. I've only just been able to get back to this project due to other work. 

when HTTP_REQUEST

{

    STREAM::disable

    HTTP::header remove "Accept-Encoding" 

    set original_uri [HTTP::uri]

    HTTP::uri "/test${original_uri}"

}

Apologises for my understanding of this but my iRules knowledge is basic

So when there is an HTTP request 

set original_uri [HTTP::uri]   >>  set the original_uri means keep the original uri and store it as a variable? This would be  https://example.com

HTTP::uri "/test${original_uri}" } >> this is the replacement, so the $ gets the variable and appends the test to it https://example.com/test

Is it possible to make the following happen?

https://example.com to https://different.name.com:666

{

    STREAM::disable

    HTTP::header remove "Accept-Encoding" 

    set original_uri [HTTP::uri]

    HTTP::uri "https://different.name.com:666"

}

Within the response, do I just substitute in as follows

when HTTP_RESPONSE

{

if {[string match "https://different.name.com:666*" $loc]}

HTTP::header replace "Location" [string map {"https://different.name.com:666" "https://example.com"} $loc]

Would the stream profile be like this?

  Thanks

Thats correct, a single uri to servers on different subnets

 I have a number of pools, each has a specfic node in it, listening on a port - 666

Each pool has a remote test client that connects to the pool

I'd like all test clients to hit the same uri of https://example.com then be redirected to a specific server (based on their source IP)

client 1 uses 192.168.1.1

    goes to pool A and https://example.com redirects to hostnameA.test.com:666

client 2 uses 192.16821

   goes to pool B and https://example.com redirects to hostnameB.test.com:666

client 3 uses 192.16821

   goes to pool C and https://example.com redirects to hostnameC.test.com:666

I want the node name to remain hidden from client, currently I see the server name in the response, I just want the client to only ever see https://example.com if possible

Thanks again

There is a redirect

The solution is partially working on a single test network.

Client connects to uri > f5 has a re-write profile > that changes the uri to be the name of the back end server (Keycloak)

https://hostnameA.test.com:666 

In the browser of the client I get the https://hostnameA.test.com:666 which exposes the server name

I'd like the client to not see this.

I have this on multiple test environments, each with their own dedicated server 

....

I will try this out tomorrow, thank you for your input, its very much appreciated
