Hi Hans,
processes don't know each other and i.g. you can't control which
instance of
your Application responds to the next request, this means:
Apache (T=0)
|
+ < Application (Process 0)
| @@flock = nil
|
|
+ > Fork'd Application (Process 1)
| @@flock = nil
|
+ > Fork'd Application (Process 2)
@@flock = nil
---
Apache (T=1)
|
+ < Application (Process 0)
| @@flock = nil
|
|
+ > Fork'd Application (Process 1)
| @@flock = nil
|
+ > Fork'd Application (Process 2) < - REQUEST 1 *200*
@@flock = nil
---
Apache (T=2)
|
+ < Application (Process 0)
| @@flock = nil
|
|
+ > Fork'd Application (Process 1) < - REQUEST 2 *500*
| @@flock = nil
|
+ > Fork'd Application (Process 2)
@@flock = true
If you use Mongrel or Thin whereas only a single Process for your
application
exists the class variable is always the same.
Thin (T=0, Process 0)
|
+ <> Application
@@flock = nil
---
Thin (T=1, Process 0)
|
+ <> Application < - REQUEST 1 *200*
@@flock = nil
---
Thin (T=2, Process 0)
|
+ <> Application < - REQUEST 2 *200*
@@flock = true
---
Regards
Florian
