Http-request set-path not working

Help!
1

I am using haproxy version 2.0.6. Following are the relevant front and back ends:

frontend test
bind 127.0.0.1:1234
mode http
option httplog
option http-buffer-request
acl receipt req.body -m reg data
use_backend receipt_back if receipt
default_backend prod

backend receipt_back
http-request set-path /app2/receipt.jsp <------------------
mode http
balance roundrobin
option forwardfor
server SERVER-1 192.168.1.1:443 ssl verify none check

Everything is working fine but the line http-request set-path /app2/receipt.jsp is not working. The default URL is /app1/receipt.jsp and logs are showing that although the backend selected is receipt_back, the URL is still /app1/receipt.jsp

Never mind. The issue is that by default HAProxy logs the request URI it receives from the client and not the request URI after set-path that is why the logs will always show the original req.uri. The above configuration works as intended. Thanks
