Getting the current proxy pac configuration

This is done using tcl for convenience. If you do not have it installed you can download freewrap executable and rename freewrap.exe to wish.exe or freewrapTCLSH.exe to tclsh.exe.

Registry Key : HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\
REG_SZ AutoConfigURL = https://<your url>/proxy.pac
REG_DWORD ProxyEnable = 0

This is the tcl script:

package require http

set pacURL [registry get {HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings} AutoConfigURL]
puts $pacURL

set conn [::http::geturl $pacURL]
::http::wait $conn
puts [::http::data $conn]
