Proces killed after http post without ConentType header

[Bardo Bakker <bardobakker@xxxxxxxxx>]

Hi,

I wrote some software which post a binary (image) to our server.
After a reboot (due to resize HDD), the server has some post issues.
It hangs at the end of a http post without the content type header set.

I would like to know: is this a bug, configuration mistake, or miss interpertation of http post protocol...

Tank you!
