290 | =item keepalive => <boolean> |
|
|
291 | |
|
|
292 | Enables (default disable) the SO_KEEPALIVE option on the stream socket: |
|
|
293 | normally, TCP connections have no time-out once established, so TCP |
|
|
294 | conenctions, once established, can stay alive forever even when the other |
|
|
295 | side has long gone. TCP keepalives are a cheap way to take down long-lived |
|
|
296 | TCP connections whent he other side becomes unreachable. While the default |
|
|
297 | is OS-dependent, TCP keepalives usually kick in after around two hours, |
|
|
298 | and, if the other side doesn't reply, take down the TCP connection some 10 |
|
|
299 | to 15 minutes later. |
|
|
300 | |
|
|
301 | It is harmless to specify this option for file handles that do not support |
|
|
302 | keepalives, and enabling it on connections that are potentially long-lived |
|
|
303 | is usually a good idea. |
|
|

|
|
306 | |
|
|
307 | BSD majorly fucked up the implementation of TCP urgent data. The result |
|
|
308 | is that almost no OS implements TCP according to the specs, and every OS |
|
|
309 | implements it slightly differently. |
|
|
310 | |
|
|
311 | If you want to handle TCP urgent data, then setting this flag gives you |
|
|
312 | the most portable way of getting urgent data, by putting it into the |
|
|
313 | stream. |
