Clears any compression format headers so that both parties are forced to communicate in the clear. Generally I have a split terminal with client transmissions scrolling down on the left side and server responses scrolling on the right side.
This is something that I find myself using daily, especially when programming embedded devices that talk to a server (esp32, for example). It's nice to be able to switch to a screen and see all the messages scroll by, especially with esp32-type projects where there really is no good way to figure out what the device didn't like about the response (or in what way the request was mangled so that the server program didn't like it).
I use it on web projects as well, because frankly, the three-finger-salute I have configured for switch screens/desktops is much faster than clicking around in devtools.
