如何提高重定向代码的效率

我在所有ASP页面的顶部都有这个包含,重定向到所有页面的https,不在名为“words”和“generators”的文件夹中。我不希望他们在ssl上,因为我听说转向SSL会对AdSense收入产生重大影响。

我还重定向,以便如果用户最终使用单词和生成器文件夹中的SSL版本的页面,则会将它们带到非ssl页面。

最后我有一个从页面的www版本重定向到非www版本,例如www.test.co.uk到test.co.uk

我的代码如下。

我想知道我是否以非常耗费资源的方式执行此操作,并且如果有更好的方法使用Web配置或类似的方式来执行此操作,或者是否如果它没有被破坏,请不要解决它?

我意识到我的代码非常基本且笨重,抱歉。

SERVER_NAME =  lcase(Request.ServerVariables("SERVER_NAME"))
SCRIPT_NAME =  lcase(Request.ServerVariables("SCRIPT_NAME"))
QUERY_STRING = lcase(Request.ServerVariables("QUERY_STRING"))
SECURE_MODE =  lcase(Request.ServerVariables("SERVER_PORT_SECURE"))

str0 = request.servervariables("url")
arrFolderData = Split(str0, "/")
strLastFolder = arrFolderData(UBound(arrFolderData)-1)
words_str = instr(strLastFolder,"words")
gens_str = instr(strLastFolder,"generators")

'' if page = http, and page is not in "words" or "generators" folder then redirect to https version of page

if SECURE_MODE = 0 AND words_str = 0 AND gens_str = 0 then

    SERVER_NAME = replace(SERVER_NAME, "www.", "")

    go_to_url = ""
    go_to_url = go_to_url & "https://"
    go_to_url = go_to_url & SERVER_NAME
    go_to_url = go_to_url & SCRIPT_NAME

    if QUERY_STRING <> "" then
        go_to_url = go_to_url & "?" & QUERY_STRING
    end if

    Response.Buffer = true
    Response.Status = "301 Redirect"
    Response.AddHeader "Location", lcase(go_to_url)
    Response.End

end if

'' if page = https, and page is in "words" or "generators" folder then redirect to http version of page

if SECURE_MODE = 1 AND (words_str = 1 OR gens_str = 1) then

    SERVER_NAME = replace(SERVER_NAME, "www.", "")

    go_to_url = ""
    go_to_url = go_to_url & "http://"
    go_to_url = go_to_url & SERVER_NAME
    go_to_url = go_to_url & SCRIPT_NAME

    if QUERY_STRING <> "" then
        go_to_url = go_to_url & "?" & QUERY_STRING
    end if

    Response.Buffer = true
    Response.Status = "301 Redirect"
    Response.AddHeader "Location", lcase(go_to_url)
    Response.End

end if


'' redirect to non "www" version of page
if left(SERVER_NAME,3) = "www" then

    SERVER_NAME = replace(SERVER_NAME, "www.", "")

    go_to_url = ""
    go_to_url = go_to_url & "http://"
    go_to_url = go_to_url & SERVER_NAME
    go_to_url = go_to_url & SCRIPT_NAME

    if QUERY_STRING <> "" then
        go_to_url = go_to_url & "?" & QUERY_STRING
    end if

    Response.Buffer = true
    Response.Status = "301 Redirect"
    Response.AddHeader "Location", lcase(go_to_url)
    Response.End

end if

感谢@Carlos Aguilar Mares的帮助,我能够用以下代码替换上面的代码:

是的,如果使用URL重写并在网络中进行配置,这可以很容易地完成并且可能更快(不再在脚本中,不再解析代码,本机代码中的正则表达式和逻辑,加上更易于维护等)。配置。

规则如下所示:

<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <rule name="NON HTTPS" enabled="true" stopProcessing="true">
                    <!-- Redirect to HTTPS as long as it does not end in words/generators -->
                    <match url="(.*)" ignoreCase="false" />
                    <conditions>
                        <add input="{HTTPS}" pattern="off" />
                        <add input="{URL}" pattern="(words|generators)$" negate="true" />
                    </conditions>
                    <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" appendQueryString="true" redirectType="Permanent" />
                </rule>
                <rule name="HTTPS" enabled="true" stopProcessing="true">
                    <!-- Redirect to HTTPS as long as it ends in words/generators -->
                    <match url="(.*)" ignoreCase="false" />
                    <conditions>
                        <add input="{HTTPS}" pattern="on" />
                        <add input="{URL}" pattern="(words|generators)$" />
                    </conditions>
                    <action type="Redirect" url="http://{HTTP_HOST}/{R:1}" appendQueryString="true" redirectType="Permanent" />
                </rule>
                <rule name="Canonical HostName"  stopProcessing="true">
                    <!-- Redirect to the non-www host -->
                    <match url="(.*)" />
                    <conditions>
                        <add input="{HTTP_HOST}" pattern="^www\.(.*)$"  />
                    </conditions>
                    <action type="Redirect" url="http://{C:1}/{R:1}" appendQueryString="true" redirectType="Permanent" />
