Dynamic proxy user name

[jsvachon2]

Hi,

some proxy providers (such as Luminati/BrightData) are using dynamic user name to their proxy to allow their customer to specify things like the desired location of the proxy or to specify a session name to enforce IP rotation.

Are there any ways to control proxy definition through environment variables or http headers?

Something like:

http <proxy_ip> <proxy_port> ${PROXY_USERNAME} <proxy_password>

Thanks
