 ### Progressive Web App HIJAX Page Load
 
-When HIJAX is enabled, Sargasso automatically captures `<a href="..">` tags and calls the LoadPageHandler instead of allowing the browser load and replace entire pages natively. Usually a web site or app has a boilerplate html wrapper that is the same for every page and well defined content areas that change from page to page. When pages are loaded via HIJAX only the changed content is merged with the current page, replacing elements marked with `data-hijax` leaving heavy weight wrapper elements, persistent javascript, css and sargasso elements intact. You can define as many dynamic elements in the wrapper as needed. Following this scheme allows for deep linking, and search engine discovery while also speeding page load for real browsers.
