What is main difference between X-Forwarded-For (No Via) and X-Forwarded-For (+ Via)
How to differentiate what is main difference between X-Forwarded-For (No Via) and X-Forwarded-For (+ Via)
Which option to use X-Forwarded-For (No Via) or X-Forwarded-For (+ Via)
|Steps to Reproduce:|
The difference is that the header is slightly different. With +VIA you are seeing the proxy address used to inject the header as part of the request, indicating from where (via) the header was injected. With no VIA, you just have the X-Forwarded-For header with no indication of where this header was injected.
With No VIA
