PH:
The proxy blocked the server’s response, because it was invalid,
incomplete, dangerous (cache control), or matched a security filter.
In any case, an HTTP 502 error is sent to the client. One possible
cause for this error is an invalid syntax in an HTTP header name
containing unauthorized characters. It is also possible but quite
rare, that the proxy blocked a chunked-encoding request from the
client due to an invalid syntax, before the server responded. In this
case, an HTTP 400 error is sent to the client and reported in the
logs.
