how about

  if [ "$httpd_only" != "${httpd_only#/}" ]; then

that should do the same and does so without external processes.

This is also not really portable. I suggest the use of

  command -v $http_only

first, that's shell-internal as well, and second, it's
/more/ portable than which, but also not entirely.
