Replace Filter Demo

A demo project which demonstrates the work of javax.servlet.Filter capable of escaping / modifying / removing a part of JSON request based on specified criteria.

How it works

1. A request is being dispatched with a matching criteria configured in ReplaceUtils.kt
2. The ReplaceFilter detects it
3. Already mentioned ReplaceUtils.kt picks up and applies a replace function for the matched string
4. The resulted JSON with replaced string gets processed further down (other HTTP filters, servlets, etc.)
