Nginx FastCGI response buffer sizes

By default when Nginx starts receiving a response from a FastCGI backend (such as PHP-FPM) it will buffer the response in memory before delivering it to the client. Any response larger than the set buffer size is saved to a temporary file on disk.

This process is outlined at the Nginx ngx_http_fastcgi_module page manual page.

Introduction
Determine actual FastCGI response sizes
Setting the buffer size
Verifying results

Use curl to get the JSON response for the latest release
Use grep to find the line containing file URL
Use cut and tr to extract the URL
Use wget to download it

curl -s https://api.github.com/repos/jgm/pandoc/releases/latest \
| grep "browser_download_url.*deb" \
| cut -d : -f 2,3 \
| tr -d \" \

If you haven’t worked with JavaScript in the last few years, these three points should give you enough knowledge to feel comfortable reading the React documentation:

We define variables with let and const statements. For the purposes of the React documentation, you can consider them equivalent to var.
We use the class keyword to define JavaScript classes. There are two things worth remembering about them. Firstly, unlike with objects, you don't need to put commas between class method definitions. Secondly, unlike many other languages with classes, in JavaScript the value of this in a method [depends on how it is called](https://developer.mozilla.org/en-US/docs/Web/Jav

	* XMPP Connection manager.
	*
	* Thie class is the main part of Strophe. It manages a BOSH connection

	* authentication.

	* After creating a Strophe.Connection object, the user will typically
	* call connect() with a user supplied callback to handle connection level

	# How it works:
	# When used with SSH, git sends the path to the repository in the SSH command.
	# @see: https://github.com/git/git/blob/e870325/connect.c#L1268
	# We extract this info and search for a key with the name.
