Apache is a fantastic open-source web server. It’s stable, secure, and mature. Furthermore, it has support for add-on modules called apps. This article covers the basics of how to enable Apache apps in your server environment and pinpoint where you can take things further with interactive applications.
Apache apps are a way to extend the functionality of Apache. Unlike traditional web apps that run on the same server, Apache apps use a special protocol to create an app container on the server. That container will run the requested app in a separate process. This allows Apache apps to handle more responsibility than traditional web apps, such as serving different content types and handling different access privileges. Apache apps are especially useful for server environments that have multiple web servers. Environments like this often have a gateway server that directs traffic to the other web servers. For example, the gateway server may be set up to redirect traffic to the main web server when users type in the domain name. A user may be able to access the main page, but is redirected to the login page. However, when the user types in the login page URL, the gateway server redirects the user to the login page for the other web server.
Installing an app is simple. Apache will automatically look for and install apps on the server. There are two ways to install apps. The first is to use an app repository, which is a collection of code hosted on a remote server. The other option is to install apps manually.
Apache apps are provided as shared libraries that are stored in the /usr/lib directory. When Apache is running, it will look for those libraries in that directory. It will then use the code inside the libraries to parse the content and serve it to the browser. You can think of apps being like a virtual machine (VM) inside the Apache server. Apache apps are designed to handle specific types of content, such as audio or video. In fact, most apps only handle one type of content. This is convenient because your web server only has to know how to handle that type of content. Apache apps can also handle different access privileges. This can be useful in server environments that have different types of access, such as one type of access to certain content and another to the backend resources needed to serve that content.
The majority of apps provided by Apache will work out of the box once you have installed them. However, Apache apps come with a few additional features that can be useful for interactive apps. First, Apache apps can be run in a threaded environment. That means that the app will run in a separate thread from the main Apache server process. This is useful for apps that have a ton of I/O operations, such as those that consume large amounts of bandwidth. Second, Apache apps can be configured to use a proxy server when an app is requested. This is useful for apps that require an external API. For example, you may want to configure your app to use a specific API, such as Facebook’s Graph API. If a user requests your app through a browser, the browser will proxy the request to the API server, and you can handle the request properly.
Apache apps are a handy way to extend the functionality of your web server. They allow you to handle different content types, handle different access privileges, and can even run in a threaded environment. There are a handful of apps that are especially useful, such as apps that handle streaming media and apps that can handle different content types. Apache apps are easy to set up and require little maintenance. However, you’ll need to keep an eye on them to make sure they don’t get out of hand. Try to use Apache apps for specific purposes and don’t try to use them for everything. You can also use the features mentioned in this article to make your apps even more useful.
