Is it possible for Chilkat to use a Proxy PAC script for HTTP proxies?
First some information about what is in a PAC file:
A proxy auto-config (PAC) file defines how web browsers and other user agents can automatically choose the appropriate proxy server (access method) for fetching a given URL.
A PAC file contains a JavaScript function "FindProxyForURL(url, host)". This function returns a string with one or more access method specifications. These specifications cause the user agent to use a particular proxy server or to connect directly.
Chilkat is unable to use a PAC file because it would need to have a fully built-in Javascript engine to interpret and run the Javascript. A browser, such as FireFox or IE, contains a Javascript engine and therefore it's possible in that environment. However, it's not possible w/ Chilkat.
