Facebook Page Load Concept -


i know page reload concept via ajax without page refresh. facebook pages reload through normal page load. sidebar's not loading reload content area.

how possible?

advance friends

facebook uses bigpipe

the general idea decompose web pages small chunks called pagelets, , pipeline them through several execution stages inside web servers , browsers. implemented entirely in php , javascript.

clicking , taking action on webpage initialize/executes pagelet, response generates iframe or ajax well. read response , show small chunk, not refresh page.
