Exchange sac in King's gambit

I seem to arrive at this position a lot and wonder if it is sound for white.  Thanks!

Why not 8. Nbd2?  or 9. gxf3?

That rook sac cannot be sound, black has a solid position and a safe king, you have no positives in the position. 

 Well, I guess that's what I should be doing, but I think I would probably play c3 a bit earlier to own the center and keep the knight off that square in the first place.

 A few months ago I started playing the rook move, and just assumed that I had sufficient compensation because I am better developed.  However, as the previous poster said, it seems easy enough for black to defend.

Anyway, thanks for the responses.  I feel like I've gotten adequate compensation for looking silly in this post, because I got a response from the famed 'batgirl'!   A sound sacrifice indeed :)

famed? 

hardly :-D

!

Try 4. d4

you wrote that what you like about the opening is that white dominates the f-file. which pieces are good on files? yes the rook you traded off:)
