#Caching Servlet

Requirements

Answering my own question on StackOverflow

• Create a Java Server Example that caches POST Response and responds to GET with identical URL

• I wanted to Create a Backend-less option so I am using Simple File based caching.

• Create a barebone example without any frameworks on either sides (client or Server). However, I had to use log4j to get logging work. If you have any suggestions or PR I am open to "fixing" this.

• Use Maven so that it can be run with IDE.

This was more of an idea I wanted to tinker around. Do not do this in Production Environment. Any suggestions welcome!

Flow

Request Method	URI	Process / Result
GET	/hello	Landing Page
POST	/hello/abc with {JSON: data}	Cache Request UI -> {JSON: data}
GET(in another Tab)	/hello/abc	Respond with Cached Data: {JSON: data}

Server Shutdown : Write all accumulated cache to Java Properties File

Server Startup : Read Properties file into HashMap to serve requests.

Clean Install and Run
