Redirection iRule Request for subsites

Hello

 

I am pretty new to F5 and would like to see if someone can help me with a redirection iRule.

 

The redirection should retain path after the second location or the subsites. So I am looking for something like:

1. when going to http://abcsp/sites/apps should be redirected to https://apps.abcsharepoint.example.com/

2. when going to http://abcsp/sites/apps/SomethingSomething should be redirected to https://apps.abcsharepoint.example.com/SomethingSomething

3. when going to http://abcsp/Anythingotherthansites should be redirected to https://abcsharepoint.example.com/

 

What I have in place right looks something like this:

 

when HTTP_REQUEST {

switch -glob [string tolower [HTTP::host]] {

"abcsp" {

if { [HTTP::uri] starts_with "/sites/apps/" } {

HTTP::redirect "https://apps.abcsharepoint.example.com/"

}

elseif { [HTTP::uri] starts_with "/" } {

HTTP::redirect "https://abcsharepoint.example.com/"

}

}

}

}

 

This is doing only 1 and 3. 2 is missing... 

 

Thanks in advance!

    So if you want to do this programmatically then you need to retrieve the parts of the path. To do that, use the command [ getfield [HTTP::path] "/" <field number> ] getfield HTTP::path. You can also use the tcl split command to split the path into a list and check the list contents with lindex

    Seems pretty simple - the pseudocode would be:

    if field 2 == "sites"
    if field 3 != ""
        then Host = field 3.blahblah.com
    endif
    if field 4 != ""
        then new URI = /field3
    endif
    redirect to $Host$URI
else
    redirect to other page
endif

    Hopefully you can work it out from this
