ratproxy-report - report generator for the ratproxy tool SYNOPSIS
ratproxy-report ratproxy.log DESCRIPTION
This is essentially a prettyprinter for ratproxy logs. It removes dupes, sorts entries within groups, then sorts groups base don highest priority within the group, and produces some nice HTML with form replay capabilities. OPTIONS
ratproxy-report takes no options, only the name of the ratproxy-generated log file, and displays the generated HTML file on standard out- put. ENVIRONMENT
The environment variable RAT_URLPREFIX can be used to specify an absolute URL prefix for the trace/decompile links, if available. Otherwise they will be referenced with relative links. If the generated report will be stored in a directory different from the parameter -v to rat- proxy, then you should set this variable to that directory. EXAMPLES
