Ajax requests are canceled when hitting escape

The default behavior of most browsers is to cancel all ongoing requests when a user hits escape.  Last week this bit us in the foot, as we ‘forgot’ to expect this behavior and requests were never fired again in a single page web app.

The clean solution is of course to implement cancellation logic for all requests, but as the users were waiting for a solution, we introduced a quick fix.

By handling the keydown and keypress event on the document level, we prevented the Escape from bubbling up to the browser and cancelling all requests.

$(document).keypress(function(e) {
if(e.keyCode == 27) {
e.preventDefault();
}
}

$(document).keydown(function(e) {
if(e.keyCode == 27) {
e.preventDefault();
}
}

Help! I accidently enabled HSTS–on localhost

I ran into an issue after accidently enabling HSTS for a website on localhost. This was not an issue for the original website that was running in IIS and had a certificate configured. But when I tried to run an Angular app a little bit later on http://localhost:4200 the browser redirected me immediately to https://localhost . Whoops! That was not what I wanted in this case. To fix it, you need to go the network settings of your browser, there are available at: chrome://net-internals/#hsts edge://net-internals/#hsts brave://net-internals/#hsts Enter ‘localhost’ in the domain textbox under the Delete domain security policies section and hit Delete . That should do the trick…
