With this folder, when you deploy files to the Apache HTTP Server, it's as simple as moving files - either by copying or using FTP - to the \htdocs folder or any of its subfolders. Resources placed under this folder become accessible to incoming requests. The Apache web server has a special folder named \htdocs. JBoss, Jetty, Payara, Wildfly, WebSphere Liberty Tomcat aggregates the results and passes them to the Apache HTTP Server, and the HTTP server then sends the final response back to the client. So the typical request flow in a three-tier architecture is to first hit the Apache web server, followed by the middle-tier Tomcat server and then Tomcat interacts with databases and other resources in the back-end tier. Tomcat and the Apache HTTP Server are key components in many modern three-tier architectures. These resources are said to be part of the back-end tier - or the third tier - in a modern architecture. If a request requires it to perform logic, a Tomcat server may need to interact with a relational database, a NoSQL datastore or even a message queue.

As such, the Tomcat server is considered to be part of the middle-tier of a modern software architecture topology. If the request requires some logic, the Apache web server passes the request to the Tomcat server. If a request is for a simple, static file such as HTML or an image, the Apache web server will send that file back to the client. It is the first server-side resource a client interacts with when a request is made, and sends a final response back to the client. The Apache HTTP Server resides on this client tier. The first is known as the client or presentation tier. Modern software architectures embrace a three-tiered approach to content delivery.

The dynamic nature of Apache Tomcat comes from logic implemented in Java code form that is written and deployed to it. Tomcat, however, requires a JDK installation, along with a properly configured JAVA_HOME environment variable. It can be installed on any computer that runs a modern edition of Windows, a Linux distribution or Unix. The Apache HTTP Server has no prerequisites. Tomcat and AHS differences Here the Apache Tomcat Server runs the snoop.jsp, which uses the Servlet API to inspect the incoming request. For the longest time, the term Apache and the Apache web server were synonymous with each other, which resulted in the confusion we now face. Released in 1995, the Apache HTTP Server ( AHS) was the first Apache project and predates the establishment of the Apache Software Foundation in 1999. The confusion largely stems from the fact that the term Apache has become the colloquial name for the Apache HTTP Server. When you consider that important detail, it's easier to recognize the ill-worded nature of the original Tomcat vs. Normally, when people ask this question, they really want to know, "What's the difference between Apache Tomcat and the Apache HTTP Server?" Note that both Apache Tomcat and the Apache HTTP Server are projects maintained by the Apache Software Foundation. But, when worded that way, it contains some misleading assumptions. It's a question developers hear frequently.
