How to use an irule to append URI path in the post logon redirect parameter

Hi Andrew

Let me correct the requirement and put the request in more detail.

The client is going to come in with a logout request that looks like this

https://www-xxxxxxx.com/logout-apm?post_logout_redirect_uri=/includes/logged_out.aspx

His request would itself include the post_logout_redirect_uri in it. BUT, he would not come in with the host name defined in the post_logout_redirect_uri, only the URI part.

We need the F5 to pick up the www-xxxxxxx.com and uri included in that post_logout_redirect_uri /includes/logged_out.aspx and put them in the azure logout redirect URL

https://login.microsoftonline.com/common/oauth2/v2.0/logout?post_logout_redirect_uri=https://www-xxxxxxx.com/includes/logged_out.aspx

So we are basically defining the post_logout_redirect_uri for the azure logout page, by inserting the hostname from the initial request and the URI path mentioned in the initial post_logout_redirect_uri from the client.

If is use something like

when HTTP_REQUEST {

if { [HTTP::uri] contains "logout-apm"}

{

HTTP::redirect

https://login.microsoftonline.com/common/oauth2/v2.0/logout?post_logout_redirect_uri=https://[getfield [HTTP::host]/[HTTP::uri]"

}

}

i am not sure if i can use this in the first place, but even if this works, the URI path would include the whole path

logout-apm?post_logout_redirect_uri=/includes/logged_out.aspx again.

I am looking to set a redirect to something, and also modify specific segments of its URI path, like this post_logout_redirect_uri in this, I want to modify that in a way i fill out the post_logout sections details from the initial calls post logout section but.. add the host name in it, grabing the hostname from the initial HTTP::REQUEST
