if i have 2 sites A and B. A is the main site, B is the source of an iframe in A, does the BW used in site B have effect on the BW A

BW? What is BW ?

Bow Wow. You've never gone to a web site that had barking dogs covering Beatles songs in the background?

hahaha :P

Rofl

BW = Band width

It depends on whether or not they are hosted on the same hosting account. If they are, then yes, the traffic on Site A and Site B both push up the bandwidth use. Even though it is loading in an iframe, it is still pulling that page from the server.

and if they are on a different account/server ?

Then it would take the bandwidth from the other account.

iFrames are not a way to get around bandwidth, it's just another way to make a web site. It's all the same.

i think hes confused :P
