Subject: [PATCH v4 5/5] docs: mention when increasing http.postBuffer is valuable
Date: Mon, 20 Jan 2020 17:33:43 +0000 [thread overview]
Message-ID: <20200120173343.4102954-6-sandals@crustytoothpaste.net> (raw)
In-Reply-To: <20200120173343.4102954-1-sandals@crustytoothpaste.net>
Users in a wide variety of situations find themselves with HTTP push
problems. Oftentimes these issues are due to antivirus software,
filtering proxies, or other man-in-the-middle situations; other times,
they are due to simple unreliability of the network.
However, a common solution to HTTP push problems found online is to
increase http.postBuffer. This works for none of the aforementioned
situations and is only useful in a small, highly restricted number of
cases: essentially, when the connection does not properly support
HTTP/1.1.
Document when raising this value is appropriate and what it actually
does, and discourage people from using it as a general solution for push
problems, since it is not effective there.
