Does a cURL packet travel through the end users PC
Does a cURL packet travel through the end users PC (ie the client connecting to my webserver).
For example, if I use cURL to connect to "http://www.example.com/?username=admin&password=password", will the end user be able to see this with packet sniffing?
the cURL request is initiated from your web server, the client does not know about the requests occurrence.
Using "curl" on the server-side will not be sniffable by the user making the request.
On the other hand, if you're transferring anything sensitive, you should still be using encryption to prevent sniffing from any other third-party.
