apache rewrite PT to iRules

Hi,

I think this should be equivalent to the Apache rewrite rule:

when HTTP_REQUEST {
     Check if the host is test.domain.com and the path does not already start with /web/foo
    if {[string tolower [HTTP::host]] eq "test.domain.com"}{
        if { not ([HTTP::path] starts_with "/web/foo")}{
             Prepend /web/foo to the path
            HTTP::path "/web/foo[HTTP::path]"
        }
    }
}

And here's a version which works with a stream profile to rewrite the response content and redirect Location header from /web/foo to nothing:

when HTTP_REQUEST {
     Disable the stream filter by default
    STREAM::disable
     Check if the host is test.domain.com and the path does not already start with /web/foo
    if {[string tolower [HTTP::host]] eq "test.domain.com"}{
        if { not ([HTTP::path] starts_with "/web/foo")}{
             Prepend /web/foo to the path
            HTTP::path "/web/foo[HTTP::path]"
        }
    }
}
when HTTP_RESPONSE {
     Rewrite redirects
    if {[HTTP::is_redirect] && [URI::path [HTTP::header Location]] starts_with "/web/foo"}{
        HTTP::header replace Location [string map {/web/foo ""} [HTTP::header Location]]
    }
     Set the stream expression for text responses
    if {[HTTP::header Content-Length] contains "text"}{
        STREAM::expression {@/web/foo@@}
        STREAM::enable
    }
}
