Max-Forwards
The Max-Forwards
request HTTP header is used with the TRACE
method to limit the number of nodes (usually proxies) that request goes through. Its value is an integer value indicating the maximum amount of nodes it must visit. At each node, the value is decremented and the TRACE
request is forwarded to the next node, until the destination is reached, or the received value of Max-Forwards
is zero. The request is then sent back, except for some headers, as the body of a 200 OK
response.
If the Max-Forwards
header is not present in a TRACE
request, a node will assume that there is no maximum number of forwards.
