NAME
pactester - Tool to test proxy auto-config (pac) files. SYNOPSIS
pactester <-p pacfile> <-u url> [-h host] [-c client_ip] [-e] pactester <-p pacfile> <-f urlslist> [-c client_ip] [-e] DESCRIPTION
pactester is a tool to test proxy auto-config (pac) files. It returns the proxy config string for the given URL and the pac file. pactester uses pacparser C library for most of its functionality. OPTIONS
-p pacfile PAC file to test. Specify "-" to read from the standard input. -u url URL to test the PAC file for. -h host Host part of the URL. If not specified, it's determined from the URL. -c client_ip Client's IP address (as returned by the function myIpAddress() in PAC files). If not specified, it defaults to the IP address of the machine on which this tool is running. -e Enable Microsoft PAC extensions (dnsResolveEx, myIpAddressEx, isResolvableEx). -f urlslist A file containing the list of URLs to be tested. This is good for testing a PAC file against a set of URLs. EXAMPLES
To find out the proxy config string for the pac file "wpad.dat" and the URL "http://www.google.com": $ pactester -p wpad.dat -u http://www.google.com For a client with IP address 10.0.12.123: $ pactester -p wpad.dat -c 10.0.12.123 -u http://www.google.com For a pac file hosted at http://wpad/wpad.dat: $ curl -s http://wpad/wpad.dat | pactester -p - -u http://google.com BUGS
