Impersonating Connection Fingerprints

By default, the Proxy Saver replicate the incoming fingerprint of the connection, this means that if you connect with a real browser the outgoing connection will also have the same fingerprint. This is useful for most use cases, but sometimes you might use an http client from programming language or even command line like Curl.

For that case, you will want to impersonnate a real browser fingerprint, and this is done by using the FpImpersonate parameter.

Usage

Proxy Saver options are configured through a standard username flag notation where the key value pair is attached to the username. Currently there's only 1 relevant parameter:

By default, if no fingerprint option is selected Proxy Saver retains the original fingerprint.

Here are some examples of how to use the fingerprint options:
