| HTTrack Version 3.48-10 repeated downloading Webpage reason
Through the experiment, when the Dynamic Content Compression function of web
server IIS is closed, HTTrack Version3.48-10 will not repeat the update no
changed webpage.
Because of the different each time compression ratio on MS IIS , even if the
web page content did not change, but the web server send to the client's data
is still not the same, which can be considered to be different.
However, website client did not able to control server settings.
If the HTTrack judgment data come from the server in before decompression ,
whether the web page has real change will be different with the last received
data.
If the HTTrack judgment data come from the server in after decompression ,
willl not updated web page is not actually change , thereby reducing the
local file update, improve the efficiency of.
