Specify User Agent

[therumbucket]

Is it possible to specify which specific user agent is sent out with katana's requests? I have tried using the -H parameter and adding the user-agent as a string, however, it appears it prepends the user-agent header with my info and contains the original header info.

@therumbucket do you have an example where you noticed UA being prepended?

echo  http://0.0.0.0:65161 | ./katana -H "User-Agent: test"

Results into:

GET / HTTP/1.1
Host: 0.0.0.0:65161
Accept-Encoding: gzip
User-Agent: test

Is it not possible to specify the user-agent in headless mode?

$ echo  http://0.0.0.0:65161 | ./katana -headless -H "User-Agent: test" -j

   __        __

In headless mode, the user-agent being used is not the specified one, nor is it similar to what a normal legitimate browser might use.
