What is "pjax"
Pjax a technique that unites ajax and pushState, Created by one of the founders of Github, the PJAX library implements the technique using jQuery. To test its workings. The library allows indicating which hyperlinks will have their behavior modified and which container should be used to deposit the content returned by the request. The content returned by the request must be handled in the back end to strictly return what needs to be deposited in the container. This is possible thanks to a header added to the request that ensures your identification in the back-end.
