Request a lot of paths across many web hosts using different HTTP methods!

polypath reports a response from a host when the payload length differs a certain magnitude from previous payloads the host sent.

This was inspired by tomnomnom's tool, meg.

polypath [OPTIONS] <file>

Options:
  -H     <headers/@file>  comma-separated list/file with request headers
  -X     <methods>        comma-separated list of request methods to send (default: "GET")
  -d     <float>          minimum fractional difference in response payload length per host (default: 0.2)
  -e     <int>            print errors and exit after this many
  -h                      show usage information and exit
  -k                      allow insecure TLS connections
  -n     <int>            number of goroutines to run (default: 40)
  -s     <codes>          comma-separated list of acceptable status codes (default: "200")
  -w     <file>           wordlist of paths to try (required)

polypath expects a <file> of URLs and a wordlist of paths (-w). Then it iterates over the specified request methods (-X), sending a request to each host for a single path. It covers each host before moving to the next path, and each path before moving to the next request method (if any).

polypath only reports responses with payload lengths that are "different enough". For each request method, it keeps a record of response payload lengths from each host. When it receives a response with a payload length that is "different enough" from previous ones, it prints the result to stdout. You can tune this paramter with the -d option. For instance, increasing the fraction requires a larger difference to report a response. Lowering it to 0 requires no difference at all.
