HTTP redirect with URI replacement without using [http::host]

I am redirecting a https request when uri /ExampleWeb* is requested it is changed to /ExampleWeb/test* then is being redirected to http (all other uri will stay https). The issue I am having is that when it is being redirected using [http::host] the server in the pool doesn't have the host in its directory. So I would like to be able to redirect it to http but the only thing that stays is the uri (allowing the VIP to change the host). This is what I have currently which still keeps the http host. FYI the uri is case sensitivity so I can't use tolower. I don't know if this is the best way or to point it to a new pool and keep the uri.

 

when HTTP_REQUEST {

 

if {[HTTP::uri] contains "/ExampleWeb"}{

 

log "Requested URL is [HTTP::host][HTTP::uri]"

 

HTTP::uri [string map {"/ExampleWeb" "/ExampleWeb/text"} [HTTP::uri]]

 

HTTP::redirect "http://[HTTP::host][HTTP::uri]"

 

}

 

}

    if i understand correctly, you do not need HTTP::redirect command. you just create http pool and assign to virtual server.

    The issue I am having is that when it is being redirected using [http::host] the server in the pool doesn't have the host in its directory.

    you can use HTTP::header to change host header value.

    HTTP::header replace Host (new host header value)

      Thanks nitass. This is what I ended up using. There is probably a better cleaner way to do this (I'm new to irules) but it is working as expected now. when HTTP_REQUEST { if {[HTTP::uri] contains "/ExampleWeb"}{ log "Requested URL is [HTTP::host][HTTP::uri]" HTTP::uri [string map {"/ExampleWeb" "/ExampleWeb/test"} [HTTP::uri]] switch -glob [HTTP::path] { "ExampleWeb/test*" { virtual test-instance-80 } } } }
