If you’ve worked with WordPress for any length of time especially when it comes to using some type of Ajax functionality, then you’ve likely heard the phrase “use WordPress as a proxy” at some point.
And even if you haven’t the odds that you’ve actually done it are pretty high.
Though I think that, as time moves forward, we’re going to eventually see the REST API replace the traditional ways that we’ve used Ajax but that’s likely a different story for another time.
So what does it mean to use WordPress as a proxy whenever you’re working with Ajax requests? It requires a little bit of understanding cross-site requests, how routing a request through WordPress works, and then parsing the response.
