Hello. Hope your new year is going fine. If you do not mind 
I come back to this point, I thought perhaps I can make a 
suggestion in response to your observation that Httrack 
downloads the file always again if it seems that the file 
has changed. Is it possible to add an option in the limits 
or flow control section for one of the two things below.

- maximum number of times a downloaded html and other files 
can be overwritten, regardless if the file changed or not, 
regardless if downloading an entire website or updating an 
existing website ?
- or a simpler option, enable/disable to only overwrite one 
time. Can still update because can overwrite once, but 
prevents multiple downloads to the same filename.

Thanks and keep up the good work. Any design you come up 
with could help speed up the program over my slow modem 
connection.

Joseph
