Request Rewrite

Prepare environment

Please refer to API7 EE Introduction to complete the environment preparation.

Create route with proxy rewrite

Create an API, this time we don't need to open the plugin.

Set a special uri that is not /anything.

Next we set two things,

• Rewrites path by replacing prefix, rewriting /otherapi to /anything.
• Adds a header and removes a client's header.
  • X-Test = JustForPoC will be added
  • X-Delete form client will be deleted

Test
