How to limit client body/upload size?

[Gilles Van Vlasselaer]

Hi, we are currently migrating servers and decided to drop NGINX in 
favour of HAProxy, however we had issues in the past where people would 
bomb us with massive file uploads on some services. Is there an 
equivalent like nginx's 'client_max_body_size' directive?

Thanks in advance,
