HTTPProxy "eats" some contents bytes, content-lenght won't match

[etj]

Not all of the input bytes are returned to the caller, so the content-lenght header will not match the real content. It may bring to:

• errors on client side
• timeout waiting for the missing bytes
• completely corrupted binary contents.

Observed in a WMS getCapability on Comune-FI: the CR were filtered out.
