Redirecting an specific URI to another one on the same domain

Hi all,

 

I'm trying redirect an specific URI to home page, but it's not working fine.

 

I have te following iRule configured:

 

when HTTP_REQUEST { if { ([HTTP::host] equals "subdomain.domain.com") and ([HTTP::uri] ends_with "/identityiq/dashboard/editPreferences.jsf") } { HTTP::redirect "https://[HTTP::host]/identityiq/home.jsf" } }

 

The objective is "block", doing a redirect on URI /identityiq/dashboard/editPreferences.jsf redirecting to /identityiq/home.jsf

    Hi Paulo,

    for a redirect within a given website site (aka. same protocol and hostname:port), you don't need to specify the protocol, hostname:port). Redirect destination starting with a / (slash) are always considered relativ to the website root-web.

     

    when HTTP_REQUEST { 
    if { ( [string tolower [HTTP::host]] equals "subdomain.domain.com" ) 
     and ( [string tolower [HTTP::path]] equals "/identityiq/dashboard/editpreferences.jsf" ) } then { 
        HTTP::redirect "/identityiq/home.jsf" 
    }
}

     

    Note: Other interesting redirect shortcuts are "//domain.de/folder/file" (same protocol as before but new host/folder/file), "./file" same protocol, same host, same folder(s) but different file)

    Note: You have mentioned that this code has security purposes. Because of that I've added [string tolower] syntax to make the comparsion case insensitive and also changed the matching for the blocked URL to [HTTP::path] equals /.... Without those tweaks the blocking mechanism can be bypassed very easy.

    Cheers, Kai
