Cisco Cisco Web Security Appliance S170 ユーザーガイド

(Optional) In the Hostnames for Serving PAC Files Directly section, configure hostnames and associated 

file names for PAC file requests that do not include a port number:

Submit and commit your changes.

Create and publish a PAC file.

Enter a URL in your browser’s PAC file configuration area that points to the PAC file location. 

The following are valid URL formats if the Web Security appliance is hosting the PAC file:

http://server_address[.domain][:port][/filename] | http://WSAHostname[/filename]

where WSAHostname is the hostname value configured when hosting the PAC file on a Web Security 
appliance. Otherwise the URL format will depend on the storage location and, in some cases, on the 
client.

.

Create a PAC file called 

wpad.dat

 and publish it to a web server or Web Security appliance (the file must 

be placed in a web server’s root folder if you intend using WPAD with DNS).

Configure the web server to set up 

.dat

 files with the following MIME type:

application/x-ns-proxy-autoconfig

 

The hostname that the PAC file request must include if the Web Security 
appliance is to service the request. As the request does not include a port 
number, it will be processed through the Web Proxy HTTP ports (e.g. port 
80) and must be distinguishable as a PAC file request through this hostnam-
evalue.

The PAC file name that will be associated with the hostname on the same 
row. Request to the hostname will return the PAC file specified here.

Only PAC files that have been uploaded are available for selection.

Adds another row to specify additional hostnames and PAC file names.
