* This file defines four types of data structures: singly-linked lists,
* singly-linked tail queues, lists and tail queues.
*
* A singly-linked list is headed by a single forward pointer. The elements
* are singly linked for minimum space and pointer manipulation overhead at
* the expense of O(n) removal for arbitrary elements. New elements can be
* added to the list after an existing element or at the head of the list.
* Elements being removed from the head of the list should use the explicit
* macro for this purpose for optimum efficiency. A singly-linked list may
* only be traversed in the forward direction. Singly-linked lists are ideal
* for applications with large datasets and few or no removals or for
* implementing a LIFO queue.
*
* A singly-linked tail queue is headed by a pair of pointers, one to the
* head of the list and the other to the tail of the list. The elements are
* singly linked for minimum space and pointer manipulation overhead at the
* expense of O(n) removal for arbitrary elements. New elements can be added
* to the list after an existing element, at the head of the list, or at the
* end of the list. Elements being removed from the head of the tail queue
* should use the explicit macro for this purpose for optimum efficiency.
* A singly-linked tail queue may only be traversed in the forward direction.
* Singly-linked tail queues are ideal for applications with large datasets
* and few or no removals or for implementing a FIFO queue.
*
* A list is headed by a single forward pointer (or an array of forward
* pointers for a hash table header). The elements are doubly linked
* so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before
* or after an existing element or at the head of the list. A list
* may be traversed in either direction.
*
* A tail queue is headed by a pair of pointers, one to the head of the
* list and the other to the tail of the list. The elements are doubly
* linked so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before or
* after an existing element, at the head of the list, or at the end of
* the list. A tail queue may be traversed in either direction.

* passed as `struct http_message` through the handler's `void *ev_data`
* pointer.
* - MG_EV_HTTP_CHUNK: The HTTP chunked-encoding chunk has arrived.
* The parsed HTTP reply is passed as `struct http_message` through the
* handler's `void *ev_data` pointer. `http_message::body` would contain
* incomplete, reassembled HTTP body.
* It will grow with every new chunk that arrives, and it can
* potentially consume a lot of memory. An event handler may process
* the body as chunks are coming, and signal Mongoose to delete processed
* body by setting `MG_F_DELETE_CHUNK` in `mg_connection::flags`. When
* the last zero chunk is received,
* Mongoose sends `MG_EV_HTTP_REPLY` event with
* full reassembled body (if handler did not signal to delete chunks) or
* with empty body (if handler did signal to delete chunks).
* - MG_EV_WEBSOCKET_HANDSHAKE_REQUEST: server has received the WebSocket
* handshake request. `ev_data` contains parsed HTTP request.
* - MG_EV_WEBSOCKET_HANDSHAKE_DONE: server has completed the WebSocket
* handshake. `ev_data` is `NULL`.
* - MG_EV_WEBSOCKET_FRAME: new WebSocket frame has arrived. `ev_data` is

*

* multipart requests and splits them into separate events:
* - MG_EV_HTTP_MULTIPART_REQUEST: Start of the request.
* This event is sent before body is parsed. After this, the user
* should expect a sequence of PART_BEGIN/DATA/END requests.
* This is also the last time when headers and other request fields are
* accessible.
* - MG_EV_HTTP_PART_BEGIN: Start of a part of a multipart message.
* Argument: mg_http_multipart_part with var_name and file_name set
* (if present). No data is passed in this message.
* - MG_EV_HTTP_PART_DATA: new portion of data from the multipart message.
* Argument: mg_http_multipart_part. var_name and file_name are preserved,
* data is available in mg_http_multipart_part.data.
* - MG_EV_HTTP_PART_END: End of the current part. var_name, file_name are
* the same, no data in the message. If status is 0, then the part is
* properly terminated with a boundary, status < 0 means that connection
* was terminated.
* - MG_EV_HTTP_MULTIPART_REQUEST_END: End of the multipart request.
* Argument: mg_http_multipart_part, var_name and file_name are NULL,
* status = 0 means request was properly closed, < 0 means connection

* SSI files pattern. If not set, "**.shtml$|**.shtm$" is used.
*
* All files that match ssi_pattern are treated as SSI.
*
* Server Side Includes (SSI) is a simple interpreted server-side scripting
* language which is most commonly used to include the contents of a file
* into a web page. It can be useful when it is desirable to include a common
* piece of code throughout a website, for example, headers and footers.
*
* In order for a webpage to recognize an SSI-enabled HTML file, the
* filename should end with a special extension, by default the extension
* should be either .shtml or .shtm
*
* Unknown SSI directives are silently ignored by Mongoose. Currently,
* the following SSI directives are supported:
* &lt;!--#include FILE_TO_INCLUDE --&gt;
* &lt;!--#exec "COMMAND_TO_EXECUTE" --&gt;
* &lt;!--#call COMMAND --&gt;
*
* Note that &lt;!--#include ...> directive supports three path
*specifications:
*
* &lt;!--#include virtual="path" --&gt; Path is relative to web server root
* &lt;!--#include abspath="path" --&gt; Path is absolute or relative to the
* web server working dir
* &lt;!--#include file="path" --&gt;, Path is relative to current document
* &lt;!--#include "path" --&gt;
*
* The include directive may be used to include the contents of a file or
* the result of running a CGI script.
*
* The exec directive is used to execute
* a command on a server, and show command's output. Example:
*
* &lt;!--#exec "ls -l" --&gt;
*
* The call directive is a way to invoke a C handler from the HTML page.
* On each occurence of &lt;!--#call COMMAND OPTIONAL_PARAMS> directive,
* Mongoose calls a registered event handler with MG_EV_SSI_CALL event,
* and event parameter will point to the COMMAND OPTIONAL_PARAMS string.
* An event handler can output any text, for example by calling
* `mg_printf()`. This is a flexible way of generating a web page on
* server side by calling a C event handler. Example:
*
* &lt;!--#call foo --&gt; ... &lt;!--#call bar --&gt;
*
* In the event handler:
* case MG_EV_SSI_CALL: {
* const char *param = (const char *) ev_data;
* if (strcmp(param, "foo") == 0) {
* mg_printf(c, "hello from foo");
* } else if (strcmp(param, "bar") == 0) {
* mg_printf(c, "hello from bar");
* }
* break;

/* URL rewrites.
*
* Comma-separated list of `uri_pattern=url_file_or_directory_path` rewrites.
* When HTTP request is received, Mongoose constructs a file name from the
* requested URI by combining `document_root` and the URI. However, if the
* rewrite option is used and `uri_pattern` matches requested URI, then
* `document_root` is ignored. Instead, `url_file_or_directory_path` is used,
* which should be a full path name or a path relative to the web server's
* current working directory. It can also be an URI (http:// or https://)
* in which case mongoose will behave as a reverse proxy for that destination.
*
* Note that `uri_pattern`, as all Mongoose patterns, is a prefix pattern.
*
* If uri_pattern starts with `@` symbol, then Mongoose compares it with the
* HOST header of the request. If they are equal, Mongoose sets document root
* to `file_or_directory_path`, implementing virtual hosts support.
* Example: `@foo.com=/document/root/for/foo.com`
*
* If `uri_pattern` starts with `%` symbol, then Mongoose compares it with
* the listening port. If they match, then Mongoose issues a 301 redirect.
* For example, to redirect all HTTP requests to the
* HTTPS port, do `%80=https://my.site.com`. Note that the request URI is
