Description

The lews_connection_context_t struct encapsulates the context associated with a web server connection. It holds incoming and outgoing web server connection buffers, along with information extracted from the parsed HTTP request.

Fields

s

The socket associated with the incoming connection.

incoming_buf

A buffer containing data read from the socket. Its size is defined by the LEWS_INCOMING_CONNECTION_BUF_SIZE macro.

received_size

The size of data read from the socket into the incoming buffer.

outgoing_buf

A buffer used for accumulating data for the response. Its size is defined by the LEWS_OUTGOING_CONNECTION_BUF_SIZE macro.

filled_size

The size of data filled into the outgoing buffer.

is_response_sent

A flag indicating whether the HTTP response header has been sent.

method_pos

The position of the method string in the incoming buffer.

method_len

The length of the method string.

url_pos

The position of the invoked URL in the incoming buffer.

url_len

The length of the URL string.

params_pos

The position of the GET request parameters strings in the incoming buffer.

params_len

The length of the GET request parameters string.

header_pos

The position of the string containing the list of HTTP request header values in the incoming buffer.

header_len

The length of the string containing the list of HTTP request header values.

data_pos

The position of the beginning of the data block in the incoming buffer.

data_len

The length of the data block.
