I have a program to send POST request to a server.
I’m using cURL to send request.
My program run on Windows and Linux (on the moment Ubuntu 9.10).
When server receive request it processing it and return error code (0000 if no errors) and error description (if any).
Server’s web server is Microsoft IIS.
When I run my program at Windows it work well.
But when I run the program at Linux it hangs up for 30 seconds (cURL’s timeout) and return error “Operation timed out after 30000 milliseconds with 5 bytes received”.
As I know problem in server side – server doesn’t send response’s size and doesn’t close socket connection.
cURL logs (from Linux):

On Windows logs are almost the same, but without timeout – it close socket immediately after reciving “0000 “.
I can analyse received data and close connection if I get “0000 “, but it’s a “dirty hack”.
Any ideas?
I found the reason of the issue.
The reason is – VirtualBox.
I’m using VirtualBox to run Ubuntu. If I’m run my program from real (not virtual) PC it work fine (even on Ubuntu).
Looks like there is a bug in latest version of VirtualBox.
