Hi Kevin, Thanks for that. I've tried a few of the suggestions in the article but still cant get it to work. I tried the following HTTP_REQUEST: HTTP::respond 302 noserver Location "https://[HTTP::host][HTTP::uri]" and it works sometimes but every 3rd/4th test, it shows up the server name again. I also tried

 

when HTTP_REQUEST { set my_loc "https://[HTTP::host][HTTP::uri]" TCP::respond "HTTP/1.1 302 Found\r\n Location: $my_loc\r\n Connection: Keep-Alive\r\n Content-Length: 0\r\n " TCP::close } and it didnt work at all. Any other suggestions would be much appreciated.

 

Thanks in advance.
