This server claims that it supports segmentation, though the server is not responding to the ranged headers. This is a server side issue and cannot be fixed.

You can get files from this server by reducing the number of threads to one.

Shouldn't turbo-download-manager check it automatically and have a fallback for this situation?

inbasic commented 8 years ago

@MariasStory TDM does check for multi-threading support. The problem is with this particular server as it is claiming they support multi-threading. Beside sending the supporting header, they return 206 status code which is sent when a partial data is transmitted. So there is no way for TDM to detect the server is not handling the request as it is supposed to.

So is this happening for another domain too?

Thank you for explain.

MariasStory commented 8 years ago

@inbasic I did not see this happening for another domains. But, where one case, another may follow.

Maybe, there is a way to check for such misleading server behavior?

inbasic commented 8 years ago

That seems very rare situation for a server to send two wrong signals;

  1. wrong header
  2. 206 status code instead of 200.

Either of these two signals will lead TDM to throw an error message to warn user or reduce the number of threads to one and continue the job if possible.

I am not aware of any other checking methods.

MariasStory commented 8 years ago

OK. If there is the warning and proposed solution in it, this should not be a problem.

The download attempt with one thread could be started automatically, plus the warn. :-)
