You're right that you can't post an example here ... but you can post a link to one (or several).
It's difficult to know specifically what you mean when you refer to the "glow" (is it similar to lens flare?). Assuming you're just refering to getting your fill flash to match the late-day ambinent light, you're looking at either putting a gel on your flash, or using a reflector that has a warming cast to it (like the soft gold variety). Meter for the background light you want to preserve (making sure that you're using a shutter speed at or below your camera's flash synch speed), and then add fill flash until you get just what you're looking for.
This calls for manual exposure setting, and manual flash power setting. And you have to re-evaluate that quickly, because at that time of day, the sun is setting quickly.
Are you able to get your flash off-camera?
