Reverse Proxy
|
|
=============
|
|
|
|
In reverse proxy mode, mitmproxy accepts standard HTTP requests and forwards
|
|
them to the specified upstream server. This is in contrast to :ref:`upstreamproxy`, in which
|
|
mitmproxy forwards HTTP proxy requests to an upstream proxy server.
|
|
|
|
================== =====================================
|
|
command-line :option:`-R http[s]://hostname[:port]`
|
|
================== =====================================
|
|
|
|
Here, **scheme** signifies if the proxy should use TLS to connect to the server.
|
|
mitmproxy always accepts both encrypted and unencrypted requests and transforms
|
|
them to what the server expects.
|
|
|
|
.. code-block:: none
|
|
|
|
>>> mitmdump -R https://httpbin.org -p 80
|
|
>>> curl http://localhost/
|
|
# requests will be transparently upgraded to TLS by mitmproxy
|
|
|
|
>>> mitmdump -R https://httpbin.org -p 443
|
|
>>> curl https://localhost/
|
|
# mitmproxy will use TLS on both ends.

Host Header
|
|
-----------
|
|
|
|
In reverse proxy mode, mitmproxy does not rewrite the host header. While often useful, this
|
|
may lead to issues with public web servers. For example, consider the following scenario:
|
|
|
|
.. code-block:: none
|
|
:emphasize-lines: 5
|
|
|
|
>>> mitmdump -d -R http://example.com/
|
|
>>> curl http://localhost:8080/
|
|
|
|
>> GET https://example.com/
|
|
Host: localhost:8080
|
|
User-Agent: curl/7.35.0
|
|
[...]
|
|
|
|
<< 404 Not Found 345B
|
|
|
|
Since the Host header doesn't match "example.com", an error is returned.
|
|
There are two ways to solve this:
|
|
|
|
1. Modify the hosts file of your OS so that "example.com" resolves to your proxy's IP.
|
|
Then, access example.com directly. Make sure that your proxy can still resolve the original IP
|
|
or specify an IP in mitmproxy.
|
|
2. Use mitmproxy's :ref:`setheaders` feature to rewrite the host header:
|
|
``--setheader :~q:Host:example.com``.
|
|
However, keep in mind that absolute URLs within the returned document or HTTP redirects will
|
|
cause the client application to bypass the proxy.
