Yes, it is possible, but it is a little complicated.

Flash video over HTTP uses progressive display and download. Random access into the stream is not technically possible. It may work in some instances when the file is already in the browser's cache, but it is not truly reliable. If you are stuck with HTTP only, then the only real option is to edit your video into chunks that represent your random access points. For example, if you have a one hour video, you can make twelve videos representing five minute offsets that play to the end (ie, a 60 min file, a 55 min file, etc). There are also some techniques to use a custom server and player which inject metadata to allow random access (I know colleagues who have done this, but have never had to do it myself).

Flash video can also play over a RTMP connection. Flash Media Server provides this, as do one or two alternates. RTMP / FMS give you lots more options for streaming your video and allows for true random access into the stream. You can either purchase and host FMS yourself, or go with a hosted solution like Influxis. Some cloud based solutions are also starting to become available.
