Checks to see if there is already a <SVC_HANDLER> in the cache connected to the <remote_addr>. If so, we return this pointer. Otherwise we establish the connection, put it into the cache, and return the <SVC_HANDLER> pointer. <[NOTE]>: the <{reuse_addr}> argument does NOT control re-use of addresses in the cache. Rather, if the underlying protocol requires a "dead time" prior to re-use of its addresses (TCP is a classic example of this), <{and}> the protocol provides a means by which to defeat the dead time, setting this argument to non-zero will defeat the dead-time requirement. <{Dev. Note: We might want to consider enhancing the interface at some point so that this also controls re-use of the cache.}> Reimplemented from ACE_Connect_Strategy. |
