Work with PAC Files
PAC (Proxy Auto-Configuration)
PAC file (Proxy auto-configuration file) contains a Javascript function that determines whether a request should be sent via the proxy server. Once you have the absolute path of the PAC file on your machine, you can establish a local testing connection using one of two ways:
Via language bindings:
Add the following snippet to your test scripts:
bsLocalArgs.put("-pac-file", "pac_file_abs_path");
bs_local_args = { 'key': 'YOUR_ACCESS_KEY', 'pac-file': 'pac_file_abs_path' }
bsLocalArgs.Add(new KeyValuePair{string, string}("-pac-file", "pac_file_abs_path"));
$bs_local_args = array("key" => "YOUR_ACCESS_KEY", "-pac-file" => "pac_file_abs_path"
bs_local_args = { "key": "YOUR_ACCESS_KEY" , "-pac-file": "pac_file_abs_path"}
bs_local_args = { "key" => "YOUR_ACCESS_KEY" , "-pac-file" => "pac_file_abs_path"}
Via command-line interface:
Establish the Local Testing connection using --pac-file
flag, along with the PAC file’s absolute path.
Run the binary using the following command:
./BrowserStackLocal --key YOUR_ACCESS_KEY --pac-file pac_file_abs_path
BrowserStackLocal.exe --key YOUR_ACCESS_KEY --pac-file pac_file_abs_path
Note: We do not support authentication with PAC file at the moment.
To resolve all requests on our remote browsers and mobile devices through your PAC proxy, add --force-proxy
and --force-local
flags to the command.
Without these flags, Local binary tries to connect directly for enhanced performance.
Sample PAC file
The following function checks to see whether the hostname is localhost, and if so, whether the connection is direct. If the hostname is not localhost, the connection is via proxy.
function FindProxyForURL(url, host) {
if (isPlainHostName(host))
return "DIRECT";
else
return "PROXY proxy:80";
}
