No, it won't.  I think you're looking for the "tee" command.  Like so:

./configure | tee apache.output

will send STDOUT to both the screen and the file "apache.output".  tee can
take multiple output files.  If you want the output file to contain both
STDERR and STDOUT, do it like so:

./configure 2>&1 | tee apache.output

(assuming you're using bash, the syntax is different for tcsh.)
