HTTP Request - Long call ending with code 0

I’m using http request to call a webservice to download some files. The call is ok but there is many files. Those with small sizes present zero problems but those with big sizes return 0 as a Status Response and I can’t workaround the problem.

First I think I understand correctly that the timeout property is not relevant because the webservice is responding. Basically I tried to change this property to ten senconds and there is no problem downloading files that last minutes since the response was 200 - OK.

So Im now getting 0 as Status Response witch means bascially unhandled response, no info.

Any experience with this problem?

Clues, tips on how to debug this will be pretty welcome.

Thanks in advance,
