/*
|
|
the yacy process of getting in touch of other peers starts as follows:
|
|
- init seed cache. It is needed to determine the right peer for the Hello-Process
|
|
- create a own seed. This can be a new one or one loaded from a file
|
|
- The httpd must start up then first
|
|
- the own seed is completed by performing the 'yacyHello' process. This
|
|
process will result in a request back to the own peer to check if it runs
|
|
in server mode. This is the reason that the httpd must be started in advance.
