-// ProxyScriptDecider is a helper class used by ProxyService to determine which |
-// PAC script to use given our proxy configuration. |
-// |
-// This involves trying to use PAC scripts in this order: |
-// |
-// (1) WPAD (DHCP) if auto-detect is on. |
-// (2) WPAD (DNS) if auto-detect is on. |
-// (3) Custom PAC script if a URL was given. |
-// |
-// If no PAC script was successfully selected, then it fails with either a |
-// network error, or PAC_SCRIPT_FAILED (indicating it did not pass our |
-// validation). |
-// |
-// On successful completion, the fetched PAC script data can be accessed using |
-// script_data(). |
-// |
-// Deleting ProxyScriptDecider while Init() is in progress, will |
-// cancel the request. |
