I have a long question about the basic operation of a broswer and a web
server with frames and CGI's (i.e. ColdFusion). Suppose I have page A
with buttons b and c. The buttons request pages B and C respectively.
If I click b and c, I observe that sometimes B shows up, sometimes C,
but never B then C. I belive, perhaps incorrectly, that I can
map out any browser session into a single sequence of pages and calls
(links or forms) that fetched them.
Now suppose these are CF pages. Is it possible that even though only
one of B or C gets fetched for display, that both page requests are
processed by the CF server and therefore both pages' side-effects may
happen?
Hopefully that was easy. Okay suppose I have a frameset A, B, and C.
Suppose button ac on frame A targets frame C with page AC, and button bc
on frame B also targets frame C with page BC. Suppose I press both ac and
bc. Do both pages AC and BC get processed, or is the identical destination
recognized and lead to the surpression of one or the other? If both get
processed, then is there any limits on the sequence or is it possible
the BC would be delayed, not just after AC was displayed, but indefinitely
for a long sequence of other page requests, before showing up out of
the blue?
Finally, and this is the situation I'm actually comtemplating, suppose
frame C is actually the parent frame of subframes A and B. Does
targeting frame C cause both frames A and B to be targeted as a unit,
or does that processing take place simultaneously? I.e. does the previous
example lead to 4 page requests:
AC targeting A
AC targeting B
BC targeting A
BC targeting B
that might execute and be displayed in any order? (Here I believe I
can wrap the C frameset in Application CFLOCKs and force the two
subtargets to process as a unit, but I still have the two requests for
C to deal with.)
I fear just understanding the question might be asking a lot!-) I would
be very grateful not just for an answer, but just a pointer to a good
resource on these kinds of questions.
Thanks,
Jonathan Gingerich
