Old URL 404, compare URI with external data group file

You can use some string commands to get the string after the last forward slash:

 

 

% set uri /abc/def/ghi/jkl/mno

 

/abc/def/ghi/jkl/mno

 

 

% string range $uri [expr {[string last / $uri] + 1}] end

 

mno

 

 

So you could parse the last field of the HTTP::path in HTTP_REQUEST, save it to a variable (set uri_token [string range [HTTP::path] [expr {[string last / [HTTP::path]] + 1}] end]) and then check in HTTP_RESPONSE for a 404 status. You could then do a lookup against a string datagroup to get the updated URI. You could either retry the request using HTTP::retry to hide the change or send a 301 redirect and have the client see the change and make a new request.
