PatchSet 4043 
Date: 2007/02/14 05:43:12
Author: rousskov
Branch: squid3-icap
Tag: (none) 
Log:
- Added ICAPInitiator interface that classes initiating ICAP
  transactions must now support. The API currently has just two methods:
  one for receiving adapted message headers (indicating a successful
  ICAP transaction, at least to the point of fetching adapted headers)
  and one for receiving a notification of an aborted ICAP transaction.

  Most ICAP initiators (or their close relatives) will also need to
  implement BodyConsumer and/or BodyProducer APIs to exchange virgin
  and/or adapted HTTP message bodies with the initiated ICAP
  transaction. However, that activity is not addressed in this API.

  New AsyncCall API is used to declare the callback wrappers.
