* singly-linked tail queues, lists and tail queues.
|
||
|
*
|
||
|
* A singly-linked list is headed by a single forward pointer. The elements

|
||
|
* 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
|

|
* - MG_EV_HTTP_MULTIPART_REQUEST: Start of the request.
|
||
|
* This event is sent before body is parsed. After this, the user

|
||
|
* 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

|

|
||
|
*
|
||
|
* 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:
|
||
|
* <!--#include FILE_TO_INCLUDE -->
|
||
|
* <!--#exec "COMMAND_TO_EXECUTE" -->
|
||
|
* <!--#call COMMAND -->
|
||
|
*
|
||
|
* Note that <!--#include ...> directive supports three path
|
||
|
*specifications:
|
||
|
*
|
||
|
* <!--#include virtual="path" --> Path is relative to web server root
|
||
|
* <!--#include abspath="path" --> Path is absolute or relative to the
|
||
|
* web server working dir
|
||
|
* <!--#include file="path" -->, Path is relative to current document
|
||
|
* <!--#include "path" -->
|
||
|
*
|
||
|
* 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:
|
||
|
*
|
||
|
* <!--#exec "ls -l" -->
|
||
|
*
|
||
|
* The call directive is a way to invoke a C handler from the HTML page.
|
||
|
* On each occurence of <!--#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:
|
||
|
*
|
||
|
* <!--#call foo --> ... <!--#call bar -->
|
||
|
*
|
||
|
* 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) {

|
||
|
* 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
|
||
|
* automatically appended to the redirect location.
