Please consult this section for more information on the architecture details and some performance test results.### Reliability - *keeping high-traffic sites online since 2002*HAProxy is first known for being extremely robust. The core team developers tend to beirritated by certain bugs they fix, but this is because their job is to see themall. Most users report having never ever faced any single crash and claim that HAProxyis the most solid part of their infrastructure. Finding machines with HAProxy processesbeing up for more than 3 years is not exceptional at all!All this is not an accident, though. A lot of efforts are made in that direction, toprovide excellent observability on what is happening, and an amazing number ofprotections against bad behaviors. HAProxy is built with many checks for unacceptablesituations (impossible conditions, endless loops, etc) that in other products mightresult in service outages or data corruption, but in HAProxy will immediately result ina crash with a dump of the problem. This rigor pays off since most users have neverfaced such an issue, thanks to the few who faced them and provided useful reportsallowing to fix the problem early.The development process also encourages quality, with a long term maintenancecycle: versions are maintained for 5 years by the same developers who code thenew features. This encourages them to write high quality code and commit messagesthat correspond to the highest standards. A regression testing suite is used andrun along development by all developers and before merging code, as well as afteron a wide variety of platforms thanks to the continuous integration (CI) system.The principle of "eating one's dog's food" applies here as well: haproxy.orgruns on the latest development release. This usually helps spot a bug or two permajor version before it hits a release. But in addition it maintains a permanentThe same call, in code.
The capture above came back as markdown. These examples add a key, so you get browser rendering, proxies, and concurrency on haproxy.org.

// No selectors, no schema. Spider reads the page and names the fields.

Fields you can pull.
Spider names these from the page. The capture above came back as markdown; the same
call with return_format: "json" returns them as keys.
