You need to create or edit a proxy auto-configuration (PAC) file for use with Symantec Edge SWG (ProxySG) or Advanced Secure Gateway (ASG).
You can use the basic proxy auto-configuration (PAC) file that ships with the Symantec Edge SWG (ProxySG) or Advanced Secure Gateway (ASG) appliance. However, if you want to create custom PAC settings for your deployment, you can edit the accelerated PAC file.
The default PAC and accelerated PAC files are located here:
To modify one of these files, open the file in a text editor such as Notepad, and make your modifications.
#inline accelerated-pac EOF
<paste PAC file contents here>
<paste PAC file contents here>is the PAC file contents you copied in step 2; paste the contents here.
EOFis an end-of-file marker; choose one that does not match any string in the PAC file itself.
While the configuration and writing of PAC file script is outside the scope of the Symantec Support team, here are some resources that can assist you in writing a PAC file:
pacparser can check the correct syntax of your PAC file. You can also use it to see which proxy will be used when accessing a test URL.
