you can just use a local proxy like proxomitron and edit the headers so they are something like
In = FALSE
Out = TRUE
Key = "HTTP/1.1 303 Moved Temporarily"
Match = "*"
Replace = "HTTP/1.1 304 Not Modified"
In = FALSE
Out = FALSE
Key = "HTTP/1.1 [0-9][0-9][0-9] Moved Temporarily"
URL = "*"
Match = "HTTP/1.1 [0-9][0-9][0-9] Moved Temporarily"
Replace = "HTTP/1.1 200 OK"
In = FALSE
Out = FALSE
Key = "If-Modified-Since: Always reload pages (Out)"
Match = "*"
In = FALSE
Out = FALSE
Key = "Last-Modified: (In)"
Match = "*"
In = FALSE
Out = TRUE
Key = "Location: http://www.t-zones.co.uk/cop/adult"
Match = "*"
Replace = "src"
