Include() vs. TrapInclude()
|
|
Just thought I'd post this for anyone else that might run into a similar
situation...
The documentation seems to suggest that Include() and TrapInclude() are
interchangeable, apart from the buffering that happens. That is:
<%
$Response->Include('test.inc');
%>
should be equivalent to:
<%=
${$Response->TrapInclude('test.inc')}
%>
with respect to output.
However, TrapInclude() creates a local output buffer, whereas Include()
does not, so certain methods behave differently if they run inside an
Include() file vs. a TrapInclude() file. For example,
$Response->Clear(), $Response->End(), and $Response->Flush() produce
different results. Their behaviour is a natural consequence of local
output buffering, so just something to be aware of.
Also, when Buffering is turned on, the behaviour of $Response->End() is
not as expected given a local output buffer, as it ends the program, but
does not flush the caller's buffer, so this may be a minor bug.
