How do I configure the browser to use a proxy when needed by the target site using the Synthetic Private Agent?

[#1]

This is not possible for hosted agents.

For private agents

• Using Chrome or IE10/11
• Using Firefox

Using Chrome or IE10/11:

• Stop the agent. Log out.
• Log in as agent_user (password: Appdynamics123).
  • Note you can't do this over RDP; you need local access to the machine.
• Navigate to Control Panel > Network and Internet > Internet Options > Connections > LAN Settings.
• Enable "Use a proxy server for your LAN" and fill in the proxy server info.
• Enable "Bypass proxy server for local addresses"
• Click "Advanced". Under "Exceptions", add localhost;127.0.0.1
• Log out. Log back in as Administrator and restart the agent.

Using Firefox:

• Add the following to C:\appdynamics\browsers\firefox\<>\mozilla.cfg

• Customize the following proxy settings and add to C:\appdynamics\browsers\firefox\<<VERSION>>\mozilla.cfg
  
  

  pref("network.proxy.type", 1); // this setting may be there already; if so, replace it
  
  pref("network.proxy.http", "<PROXY ADDRESS>");
  
  pref("network.proxy.http_port", <PROXY PORT>);
  
  pref("network.proxy.no_proxies_on", "localhost, 127.0.0.1, *.server.local");
  
  pref("network.proxy.share_proxy_settings", true);

Note: Test the proxy settings by creating a synthetic job for http://www.whatismyproxy.com and checking the results.

• Here is an example of what the config could look like customized for a specific client. For information on the possible values and the effects of the Network Proxy Type, click here. 

// EXAMPLE pref("network.proxy.type", 5) 
// A 5 WAS NEEDED INSTEAD OF A 1 WITHOUT QUOTES
pref("network.proxy.type", 5);

// EXAMPLE pref("network.proxy.http", "proxy.domain.com");  
// ENTER URL OF PROXY ENCLOSED IN QUOTES
pref("network.proxy.http", "PROXY_URL_HERE");

// EXAMPLE pref("network.proxy.http_port", 8080); 
// ENTER PORT NUMBER NO QUOTES
pref("network.proxy.http_port", PROXY_PORT_HERE);

// EXAMPLE REMOVED ",*.server.local" FROM PREF
pref("network.proxy.no_proxies_on", "localhost, 127.0.0.1");

//UNCHANGED
pref("network.proxy.share_proxy_settings", true);

// EXAMPLE pref("network.proxy.type", 5) 
// A 5 WAS NEEDED INSTEAD OF A 1 WITHOUT QUOTES
pref("network.proxy.type", 5);

// EXAMPLE pref("network.proxy.http", "proxy.domain.com");  
// ENTER URL OF PROXY ENCLOSED IN QUOTES
pref("network.proxy.http", "PROXY_URL_HERE");

// EXAMPLE pref("network.proxy.http_port", 8080); 
// ENTER PORT NUMBER NO QUOTES
pref("network.proxy.http_port", PROXY_PORT_HERE);

// EXAMPLE REMOVED ",*.server.local" FROM PREF
pref("network.proxy.no_proxies_on", "localhost, 127.0.0.1");

//UNCHANGED
pref("network.proxy.share_proxy_settings", true);

We do not need:

// EXAMPLE pref("network.proxy.http", "proxy.domain.com");  
// ENTER URL OF PROXY ENCLOSED IN QUOTES
pref("network.proxy.http", "PROXY_URL_HERE");

// EXAMPLE pref("network.proxy.http_port", 8080); 
// ENTER PORT NUMBER NO QUOTES
pref("network.proxy.http_port", PROXY_PORT_HERE);

// EXAMPLE REMOVED ",*.server.local" FROM PREF
pref("network.proxy.no_proxies_on", "localhost, 127.0.0.1");

//UNCHANGED
pref("network.proxy.share_proxy_settings", true);

If type is set to 5:

pref("network.proxy.type", 5);

As 5 means - use system proxy settings.
