Dear all,
I have several questions regarding 300(Multiple
choices),301(Moved Permanently) and 302(Moved Temporarily) responses that the
Redirect Server sends. (Consider the uesr agent client register 3 locations
:L1, L2, and L3)
(1) When and under what circumstances is
each response code sent? In other words, if the user agent
client
sends the invite message to the
redirect server, what circumstances will invoke the redirect server to send the
300 response code? Besides, what
circumstances will invoke the redirect server to send the 302
response
code? It seems no differences between 300
and 302 response code.
(2) How will the UA tell the Registrar
that it has already moved TEMPORARILY? What action does the UA take when it
moves temporarily? According to the spec and the books, why
the redirect server always send 302 response code back to user agent
instead of 300 response code?
Please let me know as soon as possible any suggestions or
ideas regarding this.
Thanks and Regards,
Lai |
