Retrieving HTTP Headers with ASP

瀏覽器版本 User-Agent 識別用戶端請求的瀏覽器類型或版本號、辨別使用的作業系統、用戶代理字串、UserAgent 稱使用者代理標示瀏覽器的參數資料。

使用 ASP 內建 Request 物件，取得伺服器的設定和用戶端的使用環境 Request.ServerVariables 包含伺服器環境變數的值，環境變數涵蓋用戶端和伺服器端的各種資訊 (瀏覽器識別資料)。

Request.ServerVariables("HTTP_USER_AGENT") '取得用戶端的瀏覽器識別資料
Request.ServerVariables("HTTP_ACCEPT") '返回 Accept Header 標頭接受格式列表的的值
Request.ServerVariables("HTTP_ACCEPT_LANGUAGE") '用戶端語系環境
Request.ServerVariables("REMOTE_ADDR") '用戶真實 IP
Request.ServerVariables("HTTP_REFERER")

返回 String 使用 HTML <A> 標記將請求引用到當前頁面的頁面的 URL。如果頁面被重定向，HTTP_REFERER 為空。HTTP_REFERER 不是 HTTP 的規範成員。



ASPX 取得用戶端瀏覽器的識別資料

ASPX Request.UserAgent 可以取得用戶端的瀏覽器識別資料，也就是 User-Agent HTTP 標頭的值。通常包含了瀏覽器的名稱 Browser Name、版本 Version、作業系統 Operating System 和 語言設定等相關資訊。透過這個屬性，可以根據用戶端的瀏覽器類型來調整網頁的內容和功能。

Request.UserAgent '取得用戶端的瀏覽器識別資料
Request.UrlReferrer.ToString()
Request.UserLanguages '字串陣列、用戶端語言喜好的設定 Array
Request.UserLanguages(0) '主要語言的設定 String

Request.Browser

取得或設定關於對於用戶端瀏覽器的資訊。HttpCapabilitiesBase 命名空間 System.Web.Configuration 取得瀏覽器已定義的功能，屬性值 IDictionary。

Request.Browser.Browser '瀏覽器識別資料 String
Request.Browser.Version '瀏覽器版本 String
Request.Browser.MobileDeviceModel '行動裝置的型號名稱 Linux, Unknown
Request.Browser.MobileDeviceManufacturer '行動裝置製造商 Unknown
Request.Browser.Crawler '瀏覽器是否為 Web Crawler 搜尋引擎 Boolean


使用 Navigator.userAgentData 伺服器端的腳本語言 JavaScript、ASP、PHP、Python 來識別用戶代理字符串瀏覽器類型或版本號、讀取用戶端的瀏覽器相關資訊，針對不同的瀏覽器類型或版本號設定樣式，使用不同的的環境設置。
