1) how many URL i can add to 1 project?2) eg. www.abcd.com and
www.abcd.com/123/456 is under same url? 
3) once i put more depth, www.abcd.com will reach to www.abcd.com/123/456
right? (if there is link to there)

to confirm:
4) from www.abcd.com/index.aspx (have a link) to www.abcd.com/123/index.aspx
(this call 1 depth right?5) eg. www.abcd.com/index.aspx (link) to
www.abcd.com/123/index.aspx (link) to www.abcd.com/123/456/index.aspx
when from www.abcd.com/index.aspx to www.abcd.com/123/456/index.aspx ,
we call it depth 2??
 
6) i do put MIME: aspx to text/html
but some aspx can convert/change to html format, but some not, why? it's too
