My original site I have limited to a mirroring depth of 
three.  How do I mirror the newly added sites such that the 
mirroring depth is unlimited but does not access links or 
sites outside the newly added site itself?
Or alternatively, mirrors the new site to an unlimited 
depth, but only grabs the first page of any off site link?
Or second alternate, mirrors the new site to an unlimited 
depth, and any off site link is mirrored to an unlimited 
depth but only from its position in the hierarchical tree.  
(A problem with all such pages is that there often is a 
link to the home page, which if followed means I could be 
mirroring a very large site when only that portion 
referenced and below is of interest.)

And having fully captured the original site, how do I 
prevent HTTrack from needlessly checking the original site 
for updates, etc., but turn the engine lose on the new 
sites added?
