Finally, I was wating for months: Non-nullable types, tagged union types, and easy declaration file acquisition are definitely the biggest wins for me with this release. Now I have to wait until Webstorm Not to mention the obscene number of typescript edge case inconsistencies in the warnings, errors, and refactorings.
It also relies on a back-end database which is not much loaded.
The solution is to buy N cheap boxes and install the application on them. Install haproxy on the old one which will spread the load across the new boxes.
The cookie will be removed so that the server does not see it. This does not cause trouble in insertion mode because the cookie is put immediately in the first response, and the session is maintained to the same server for all subsequent requests in the same session.
However, the cookie will not be removed from the requests forwarded to the servers, so the server must not be sensitive to unknown cookies. If this causes trouble, you can disable keep-alive by adding the following option: If LB1 dies, nothing works anymore.
You must also use "httpclose" to ensure that you will rewrite every requests and not only the first one of each session: For example, on apache, you can use LogFormat for this: Obviously they have troubles everywhere on the web, but you can still help them access your site by using the "source" balancing algorithm instead of the "roundrobin".

It ensures that a given IP address always reaches the same server as long as the number of servers remains unchanged. Never use this behind a proxy or in a small network, because the distribution will be unfair.
However, in large internal networks, and on the internet, it works quite well. Clients which have a dynamic address will not be affected as long as they accept the cookie, because the cookie always has precedence over load balancing: Since the load-balancer becomes critical, it will be backed up with a second one in VRRP mode using keepalived under Linux.
Download the latest version of keepalived from this site and install it on each load-balancer LB1 and LB2: It is active only on one of them at any moment. To allow the proxy to bind to the shared IP on Linux 2.
Only if you know for sure that the client s will never use keep-alive eg: Both monitor the haproxy process, and lower their prio if it fails, leading to a failover to the other node. The server name will then be extracted from cookie before it is sent to the server.
In this situation, it may be desirable to tell haproxy to respect the difference in performance.
If your application scales with CPU, you may assume a very rough 2. You can inform haproxy about this using the "weight" keyword, with values between 1 and It will then spread the load the most smoothly possible respecting those ratios:ハードウェアのロードバランサは予算上厳しくなりそうだったので、仮想サーバで動作するossのロードバランサを構築する.
