% HTTPS_REQUEST_RECEIVE_START start receiving request from %1
This debug message is issued when the server starts receiving new request
over the established connection. The argument specifies the address
of the remote endpoint.

% HTTP_BAD_CLIENT_REQUEST_RECEIVED bad request received from %1: %2
This debug message is issued when an HTTP client sends malformed request to
the server. This includes HTTP requests using unexpected content types,
including malformed JSON etc. The first argument specifies an address of
the remote endpoint which sent the request. The second argument provides
a detailed error message.

% HTTP_BAD_CLIENT_REQUEST_RECEIVED_DETAILS detailed information about bad request received from %1:\n%2
This debug message is issued when an HTTP client sends malformed request to
the server. It includes detailed information about the received request
rejected by the server. The first argument specifies an address of
the remote endpoint which sent the request. The second argument provides
a request in the textual format. The request is truncated by the logger
if it is too large to be printed.

% HTTP_BAD_SERVER_RESPONSE_RECEIVED bad response received when communicating with %1: %2
This debug message is issued when an HTTP client fails to receive a response
from the server or when this response is malformed. The first argument
specifies the server URL. The second argument provides a detailed error
message.

% HTTP_BAD_SERVER_RESPONSE_RECEIVED_DETAILS detailed information about bad response received from %1:\n%2
This debug message is issued when an HTTP client receives malformed response
from the server. The first argument specifies an URL of the server. The
second argument provides a response in the textual format. The request is
truncated by the logger if it is too large to be printed.

% HTTP_CLIENT_MT_STARTED HttpClient has been started in multi-threaded mode running %1 threads
This debug message is issued when a multi-threaded HTTP client instance has
been created.  The argument specifies the maximum number of threads.

% HTTP_CLIENT_QUEUE_SIZE_GROWING queue for URL: %1, now has %2 entries and may be growing too quickly
This warning message is issued when the queue of pending requests for the
given URL appears to be growing more quickly than the requests can be handled.
It will be emitted periodically as long as the queue size continues to grow.
This may occur with a surge of client traffic creating a momentary backlog
which then subsides as the surge subsides.  If it happens continually then
it most likely indicates a deployment configuration that cannot sustain the
client load.

% HTTP_CLIENT_REQUEST_RECEIVED received HTTP request from %1
This debug message is issued when the server finished receiving a HTTP
request from the remote endpoint. The address of the remote endpoint is
specified as an argument.

% HTTP_CLIENT_REQUEST_RECEIVED_DETAILS detailed information about well-formed request received from %1:\n%2
This debug message is issued when the HTTP server receives a well-formed
request. It includes detailed information about the received request. The
first argument specifies an address of the remote endpoint which sent the
request. The second argument provides the request in the textual format.
The request is truncated by the logger if it is too large to be printed.

% HTTP_CLIENT_REQUEST_SEND sending HTTP request %1 to %2
This debug message is issued when the client is starting to send a HTTP
request to a server. The first argument holds basic information
about the request (HTTP version number and status code). The second
argument specifies a URL of the server.

% HTTP_CLIENT_REQUEST_SEND_DETAILS detailed information about request sent to %1:\n%2
This debug message is issued right before the client sends an HTTP request
to the server. It includes detailed information about the request. The
first argument specifies an URL of the server to which the request is
being sent. The second argument provides the request in the textual form.
The request is truncated by the logger if it is too large to be printed.

% HTTP_CLIENT_REQUEST_TIMEOUT_OCCURRED HTTP request timeout occurred when communicating with %1
This debug message is issued when the HTTP request timeout has occurred and
the server is going to send a response with Http Request timeout status
code.

% HTTP_CONNECTION_CLOSE_CALLBACK_FAILED Connection close callback threw an exception
This is an error message emitted when the close connection callback
registered on the connection failed unexpectedly.  This is a programmatic
error that should be submitted as a bug.

% HTTP_CONNECTION_HANDSHAKE_FAILED TLS handshake with %1 failed with %2
This information message is issued when the TLS handshake failed at the
server side. The client address and the error message are displayed.

% HTTP_CONNECTION_HANDSHAKE_START start TLS handshake with %1 with timeout %2
This debug message is issued when the server starts the TLS handshake
with the remote endpoint. The first argument specifies the address
of the remote endpoint. The second argument specifies request timeout in
seconds.

% HTTP_CONNECTION_SHUTDOWN shutting down HTTP connection from %1
This debug message is issued when one of the HTTP connections is shut down.
The connection can be stopped as a result of an error or after the
successful message exchange with a client.

of the request. The first argument specifies the amount of received data.
The second argument specifies an address of the remote endpoint which
produced the data.

% HTTP_IDLE_CONNECTION_TIMEOUT_OCCURRED closing persistent connection with %1 as a result of a timeout
This debug message is issued when the persistent HTTP connection is being
closed as a result of being idle.

% HTTP_PREMATURE_CONNECTION_TIMEOUT_OCCURRED premature connection timeout occurred: in transaction ? %1, transid: %2, current_transid: %3
This warning message is issued when unexpected timeout occurred during the
transaction. This is proven to occur when the system clock is moved manually
or as a result of synchronization with a time server. Any ongoing transactions
will be interrupted. New transactions should be conducted normally.

% HTTP_REQUEST_RECEIVE_START start receiving request from %1 with timeout %2

over the established connection. The first argument specifies the address
of the remote endpoint. The second argument specifies request timeout in

response from the server. The URL of the server is specified as an argument.

% HTTP_SERVER_RESPONSE_RECEIVED_DETAILS detailed information about well-formed response received from %1:\n%2
This debug message is issued when the HTTP client receives a well-formed
response from the server. It includes detailed information about the

This debug message is issued right before the server sends a HTTP response
to the client. It includes detailed information about the response. The
first argument specifies an address of the remote endpoint to which the
response is being sent. The second argument provides a response in the
textual form. The response is truncated by the logger if it is too large
to be printed.
