Understanding the default Nginx virtual host (or server) configuration

After you had installed Nginx, one of the first thing to do is to check whether it is running ok.

One way to do so is to use your browser to send a HTTP request to test it.

If you had installed Nginx on your local machine, then you may enter http://localhost or http://127.0.0.1 into the location bar of your browser.

When you had setup Nginx on a separate machine on your home network, you may also enter http://<ip_address_of_the_machine> in the location bar of your browser. For example, in how to host a WordPress website on a Raspberry Pi with Raspbian Buster Lite and Nginx, I had entered http://192.168.1.114 as the location to test out the Nginx server running on my Raspberry Pi.

So be it http://localhost, http://127.0.0.1, http://<ip_address_of_the_machine>, you will always see this page on your browser screen:

default welcome page of Nginx 1.14.2

In case you are wondering why your Nginx behaves this way, this post will explain what the default Nginx Virtual Host configuration does to Nginx.

How to send a HTTP request with client certificate + private key + password/secret in Python 3

When we need to create a HTTP client that communicates with a HTTP server through certificate-based authentication, we will typically have to download a certificate, in .pem format, from the server.

After we had downloaded the .pem file, the HTTP client will use the private key and certificate to authenticate itself with the HTTP server. Sometimes, the HTTP client will need to decrypt the private key with a password/secret first.

So with a .pem file and a password/secret, how can you create a HTTP client in Python 3 to send a HTTP request to the HTTP server?

In case you need it, this post shows how to send a HTTP request with client certificate + private key + password/secret in Python 3.

How to download a file via HTTP GET and HTTP POST in Java without using any external libraries

Apart from uploading a file to a HTTP server endpoint, another common task for a Java HTTP client is to download a file from a HTTP server. Even though there are many Java external libraries to help us do so, using the facilities in the Java standard runtime installation is not difficult. Furthermore, we will be able to keep our Java application leaner if we can download files without additional dependencies.

In case you need a reference, this is how to download a file via HTTP GET and HTTP POST in Java without using any external libraries.

How to send an HTTP request to a HTTP Basic Authentication endpoint in Python 3 with requests library

When you are building a Python 3 application for the Internet, you could encounter API endpoints that use HTTP Basic Authentication as the authentication mechanism.

In such a situation, using the requests library in your Python 3 code makes it easier to communicate with those endpoints.

In case you need to build a Python 3 application that sends HTTP request to a HTTP Basic Authentication endpoint, this is how you can do so with the requests library.

How to download a file via HTTP POST and HTTP GET with Python 3 requests library

When you are building a HTTP client with Python 3, you could be coding it to upload a file to a HTTP server or download a file from a HTTP server.

Previously, we discussed how to upload a file and some data through HTTP multipart in Python 3 using the requests library. In this post, let’s see how we can download a file via HTTP POST and HTTP GET.

Why Namecheap is the best domain name registrar for hosting your web server at home

Basically, a HTTP client contacts a HTTP server with an IP address. For example, when you access google.com, your web browser could be using 74.125.24.100 as the IP address to contact one of Google’s web servers. Although an IP address is what HTTP clients used for contacting HTTP servers, a domain name is easier to remember.

So if you want to host a web server at home, it is recommended that you get a domain name to make accessing your web server easier. In case you are looking for a domain name registrar to purchase a domain for your home server, this post discusses why you may want to buy from Namecheap.

Configuring Nginx and PHP 7 stack in Linux to increase or decrease file upload size limit

PHP web applications can utilize Nginx as the reverse proxy server and PHP FPM as the upstream server. Whenever you encounter HTTP file upload issues, limitation in file upload size is one common cause.

This post shows how to adjust the file upload size limit for your application running on a Nginx-PHP stack in Linux.
