Examples

Allow 10 seconds to receive the request including the headers and 30 seconds for receiving the request body:
ReqTimeout headerinit=10 bodyinit=30
Allow at least 10 seconds to receive the request including the headers. If the client sends data, increase the timeout by 1 second for every 500 bytes received. But do not allow more than 30 seconds for the request including the headers:
ReqTimeout headerinit=10 headerminrate=500 headermax=30
Allow at least 10 seconds to receive the request body. If the client sends data, increase the timeout by 1 second for every 1000 bytes received, with no upper limit for the timeout (exept for the limit given indirectly by LimitRequestBody):
ReqTimeout bodyinit=10 bodyminrate=1000

ReqTimeout Directive

Description:	Set timeout values for receiving request headers and body from client.
Syntax:	`ReqTimeout [headerinit=time [headerminrate=rate [headermax=time]]] [bodyinit=time [bodyminrate=rate [bodymax=time]]]`
Default:	`Unset; all values 0`
Context:	server config, virtual host
Status:	Experimental
Module:	mod_reqtimeout

This directive can set various timeouts for receiving the request headers and the request body from the client. If the client fails to send headers or body within the configured time, a 408 REQUEST TIME OUT error is sent.

For SSL virtual hosts, the header timeout values include the time needed to do the SSL handshake.

When an AcceptFilter is in use (usually the case on Linux and FreeBSD), the socket is not sent to the server process before at least one byte (or the whole request for httpready) is received. The header timeout configured with ReqTimeout is only effective after the server process has received the socket.

headerinit: The initial timeout for receiving the request headers in seconds. Also the timout for receiving the first byte of the request. If headerminrate is not set, the request line and all headers must be received within this time.
headerminrate: The minumum data rate for receiving the request headers in bytes/second. Whenever data is received, the timeout is increased according to this data rate.
headermax: The maximum timeout for receiving the request headers in seconds. The timeout cannot be increased above this value by headerminrate.
bodyinit: The initial timeout for receiving the request body in seconds. Also the timout for receiving the first byte of the request body. If bodyminrate is not set, the complete request body must be received within this time.
bodyminrate: The minumum data rate for receiving the request body in bytes/second. Whenever data is received, the timeout is increased according to this data rate.
bodymax: The maximum timeout for receiving the request body in seconds. The timeout cannot be increased above this value by bodyminrate
