Download using webseeds .AVI files causes DoS on server (lots of  request)

utorent 3.5.5 (bulid 45776) [32]
bt.determite_encoder_rate_for_streamers = false
bt.progresivr_pice_picker=false
bt.prioritize_partial_pices =false
bt.prio_fist_last pice =false


Downloading .avi file causes 2000 request to Apache server. It looks like  a DoS (denial-of-service attack) for administrators and automatized systems. If file have not video extension  this behavior do not occurs.

1. Get any file ~40MB.
2. Change extension to .avi.
3. Generate torrent with webseed, set pice size 16MB.
4. Download

See Apache log. You see 2005 request for this file.

1. Get the same file ~40MB.
2. Change extension to .xxx.
3. Generate torrent with webseed, set pice size 16MB.
4. Download

See Apache log. You see 4 request for this file.


I think that You try get resolution information if video filename extension in torrent file.

Can you fast fix this add this code:
if (webseedsExsist()) ignoreFileExtensionCode()
