<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Just a quick question about the Last-Event-ID header. The
spec currently says:<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>>>If the event source's last event ID string is not
the empty string, then a Last-Event-ID HTTP header must be included with the
request, whose value is the value of the event source's last event ID string,
encoded as UTF-8.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Consider the following scenario: a connection is established
and one of the events has an id of “foo”, so the last event ID of
the event source is now “foo”. The connection drops and on
reconnect, the header Last-Event-ID: foo is sent per the spec. The next stream
of events coming through do not have any IDs. The connection is dropped again. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>The question is whether or not Last-Event-ID: foo should be
sent a second time? Technically, it is the last event ID of the event source,
and the spec never mentions resetting the last event ID outside of an empty “id”
field in the stream.<o:p></o:p></span></font></p>
