Passing messages between sessions

13:51 <+integral> POE has a mechanism for passing messages between sessions, would
                  that help?

POE::Filter::Line

13:05 < jhannah> sanity check:   I'm receiving a stream of XML blocks via TCP.
                 Between each XML block is the ASCII 00 character (\x00). In
                 POE-land I'm thinking I should define a POE::Filter::Line with an
                 \x00 delim, and everything's golden?
13:06 <@dngor> sounds good to me
13:06  * jhannah jumps for joy, giddy with excitement
13:06 <@dngor> The only potential insanity: If the last block isn't terminated by
               \0 it won't be returned by the filter.
13:07 <@dngor> May be significant if the \0 is a separator rather than a terminator.
14:18 < jhannah> dngor: Thank you. I consider \x00 a record terminator, so if the
                 sender doesn't send \x00 and disconnects, then shame on them and
                 their last message is not processed.
14:42 < jhannah> laugh.... actually my XML payload is in the middle, here:
                 /^\x02(.*?)\x03/ ... I'm not sure POE::Filter::Line handles
                 this...  :)
