The Goal: Offer highly-available service to my users by routing all connections to the closest ‘cluster’ of servers in SFO, NYC, LON, and eventually Singapore. The global-balancing layer then routes the request to theleast connected server… If I’m reading your configuration correctly, you’re actually proxying from your global balancers to the balancers at each region. … Read more
var parts = location.hostname.split(‘.’); var subdomain = parts.shift(); var upperleveldomain = parts.join(‘.’); To get only the second-level-domain, you might use var parts = location.hostname.split(‘.’); var sndleveldomain = parts.slice(-2).join(‘.’);
Basically, it’s the “model” of the objects required for your business purposes. Say you were making a sales tracking website – you’d potentially have classes such as Customer, Vendor, Transaction, etc. That entire set of classes, as well as the relationships between them, would consititute your Domain Model.
You have a few options: Release an update for your app that uses a different hostname that isn’t in anyone’s cache. Same thing, but using the IP address of your server Have your users go into settings -> applications -> Network Location -> Clear data. You may want to check that last step because i … Read more
People running large(-ish) sites used to do this when they needed to break up the load between more than one server. One machine would be called www then the next one would be called www2, etc. Today, much better load balancing solutions are available that don’t require you to expose your internal machine naming conventions … Read more
if you need just catch email on domain and forward to you other mailbox, you can use http://improvmx.com/ just by adding MX records to your domain
I finally dug up the obscure command from MSDN that fixes this: ServicePointManager.DnsRefreshTimeout = 0; As I unwound all the weird things I’d tried previously, I discovered one other setting that I need along with the one above; on the request object, turn off keep-alive: request.KeepAlive = false;
You would have to do something like this: SELECT substring_index(email, ‘@’, -1) domain, COUNT(*) email_count FROM table GROUP BY substring_index(email, ‘@’, -1) — If you want to sort as well: ORDER BY email_count DESC, domain;
Dockerfile-based solution You can also fix the DNS lookup problem on a per RUN-command level: RUN echo “nameserver XX.XX.1.1” > /etc/resolv.conf && \ echo “search companydomain” >> /etc/resolv.conf && \ command_depending_on_dns_resolution Keep in mind: This will only change the DNS resolution behaviour for this one RUN command, as changes to the /etc/resolv.conf are not persistent … Read more
