My Callback URL doesn’t fit in Twitter input field - but it still works!



I have the same problem mentioned in this topic

When creating a new app, the callback URL input field only accepts a certain number of characters, which means the URL I need to use won’t fit.

I’m assuming there is nothing to be done about this, but my question is:

Why does the URL I enter still redirect correctly with the missing characters?

URL I need to enter: http://

URL (that still works with missing characters): http:// doma [missing characters here] /sub/sub/sub/sub/sub/sub/hybridauth?hauth.done=Twitter

(ignore the spaces after http://)
