# 关于OpenResty目录结构的具体说明如下

# ●bin：存放二进制可执行文件.

# ●luajit：存放LuaJIT（Lua代码解释器）相关的文件.

# ●lualib：存放Lua库文件.

# ●nginx：OpenResty整合的Nginx存放在这个目录.

# ●pod：存放用于bin/restydoc程序读取的pod文档.

# ●resty.in ndex：存放pod文档的索引.

# ●site：OPM（OpenResty Package Manager）包的存放目录.

# OpenResty主要应用在一些对性能要求非常高的场合,例如WAF（Web Application Firewall,Web应用防火墙）、

# CDN（Content Delivery Network,内容分发网络）调度、广告系统、消息推送系统、RESTful API（一种服务器接口技术）等.

# 一些知名的互联网公司如 CloudFlare 、奇虎360、新浪、京东等都在使用OpenResty相关的技术.

# OpenResty平台离不开 Nginx 和 Lua 语言,读者可通过GitHub开源平台中的openresty-best practices.

#

#        context: location

#

#        context: if in location

#

#        context: limit_except

#

#        Sets the protocol and address of a proxied server and an optional URI

#        to which a location should be mapped.  As a protocol, “"http"” or

#        “"https"” can be specified.  The address can be specified as a domain

#        name or IP address, and an optional port:

#

#            proxy_pass http://localhost:8000/uri/;

#

#        or as a UNIX-domain socket path specified after the word “"unix"” and

#        enclosed in colons:

#

#            proxy_pass http://unix:/tmp/backend.socket:/uri/;

#

#        If a domain name resolves to several addresses, all of them will be

#        used in a round-robin fashion.  In addition, an address can be

#        specified as a server group.

#

#        Parameter value can contain variables.  In this case, if an address is

#        specified as a domain name, the name is searched among the described

#        server groups, and, if not found, is determined using a

#        ngx_http_core_module.

#

#        A request URI is passed to the server as follows:

#

#        ·   If the "proxy_pass" directive is specified with a URI, then when a

#            request is passed to the server, the part of a normalized request

#            URI matching the location is replaced by a URI specified in the

#            directive:

#

#                location /name/ {

#                    proxy_pass http://127.0.0.1/remote/;

#                }

#

#        ·   If "proxy_pass" is specified without a URI, the request URI is

#            passed to the server in the same form as sent by a client when the

#            original request is processed, or the full normalized request URI

#            is passed when processing the changed URI:

#

#                location /some/path/ {

#                    proxy_pass http://127.0.0.1;

#                    proxy_pass http://127.0.0.1;

#                }

#

#            NOTE

#

#            Before version 1.1., if "proxy_pass" is specified without a URI,

#            the original request URI might be passed instead of the changed URI

#            in some cases.

#

#        In some cases, the part of a request URI to be replaced cannot be

#        determined:

#

#        ·   When location is specified using a regular expression, and also

#            inside named locations.

#

#            In these cases, "proxy_pass" should be specified without a URI.

#

#        ·   When the URI is changed inside a proxied location using the

#            ngx_http_rewrite_module directive, and this same configuration will

#            be used to process a request ("break"):

#

#                location /name/ {

#                    rewrite    /name/([^/]+) /users?name=$ break;

#                    proxy_pass http://127.0.0.1;

#                }

#

#            In this case, the URI specified in the directive is ignored and the

#            full changed request URI is passed to the server.

#

#        ·   When variables are used in "proxy_pass":

#

#                location /name/ {

#                    proxy_pass http://127.0.0.1$request_uri;

#                }

#

#            In this case, if URI is specified in the directive, it is passed to

#            the server as is, replacing the original request URI.

#

#        WebSocket proxying requires special configuration and is supported

#        since version 1.3..
