#  mitmdump

mitmdump is the command-line companion to mitmproxy. It provides tcpdump-like functionality to let you view, record, and programmatically transform HTTP traffic. See the --help flag output for complete documentation.

#  Example: Saving traffic

mitmdump -w outfile

Start up mitmdump in proxy mode, and write all traffic to outfile.

#  Filtering saved traffic

mitmdump -nr infile -w outfile "~m post"

Start mitmdump without binding to the proxy port (-n), read all flows from infile, apply the specified filter expression (only match POSTs), and write to outfile.

#  Client replay

mitmdump -nc outfile

Start mitmdump without binding to the proxy port (-n), then replay all requests from outfile (-c filename). Flags combine in the obvious way, so you can replay requests from one file, and write the resulting flows to another:

mitmdump -nc srcfile -w dstfile

See the client-side replay section for more information.

#  Running a script

mitmdump -s examples/add_header.py

This runs the add_header.py example script, which simply adds a new header to all responses.

#  Scripted data transformation

mitmdump -ns examples/add_header.py -r srcfile -w dstfile

This command loads flows from srcfile, transforms it according to the specified script, then writes it back to dstfile.
