Re: [whatwg/xhr] XMLHttpRequest (#193)

Hi There

 

Unfortunately 'navigator.sendBeacon()' is Experimental and cannot be used in
a live production application.

 

I need a solution I can rely on being around for the foreseeable future (the
site is currently used by thousands of UK train drivers for safety
training).

 

In short I want to send data to a server when a driver leaves the training
page.

 

Using a synchronous AJAX call is the only way I currently know of updating
my server in the PageHide event that works on the 5 browsers I support
(Google, Apple, Micrososft and Firefox - Desktop and Mobile).

 

This is the ONLY reason, to date, I have found to use synchronous
XMLHttpRequest I/O.

 

My reason for using this feature is because it exists, it works and does not
cause my users any problems which seems like a good reason to me.

 

Regards

 

Nigel

Please use navigator.sendBeacon() instead for that purpose. It's not a good
reason for synchronous I/O.
