c# - Instant notifications like Facebook -

June 15, 2015

I am building a social application and wondering how Facebook has received their information. As you know, Facebook's notifications are immediate. As soon as a person takes an action, people are informed.

I think they do not have a query running on the database at all times.

Can anyone tell me in the right direction? Thanks

apache - How to do an URL rewrite that works with a
pre-existing .htaccess file? -



    I have a platform that is currently available through the URL:    Www.websitecom / index.php? App = forum    Instead, I want people to be able to go here:      & lt; Ifmodule mod_rewrite.c & gt; Option - Multi Views RewriteEngine RewriteBase / RewriteCond on% {REQUEST_FILENAME}! -f Rewrite Convert% {REQUEST_FILENAME}! -d rewriteable /index.php [L] & lt; / IfModule & gt;    It seems that it should be possible, but I'm not sure how to do it.   Thank you!      This has not been tested, but something like that should be done. Add it before the first Rev.Directivity.

By doing this:    301 / redirect the forum "http://www.website.com/index.php?app = forum    However, it seems that you want to make a proper rewrite, so the first option is better,     






c# - EventSource's response has a MIME type ("text/html") that is
