需要帮助理解Coldfusion URL引荐 [英] Need help understanding Coldfusion URL Referral

问题描述

我有一个ColdFusion网站，我需要根据用户到达网页的方式显示不同的文字。

Ie，

 < cfif user comes from sitemap.cfm> 
显示此文本
< cfelse> 
显示此文本
< / cfif>有人能指出我的方向吗？

您想要查看CGI环境变量，具体来说 HTTP_REFERER （否，不是拼写错误 - ，我应该说，CGI变量的名称拼写错误。）
 
 
 
我相信 HTTP_REFERER 包含整个URL，包括查询字符串，所以你必须解析它 - 或者使用 CONTAINS 或 findNoCase（）在< cfif> 语句中：
  ; cfif findNoCase（sitemap.cfm，cgi.HTTP_REFERER）> 
显示此文本
< cfelse> 
显示此文本
< / cfif> 
  
重要的是注意 HTTP_REFERER  HTTP 到 HTTPS   - 反之亦然，我相信。 / p> 
I have a ColdFusion site on which I need to display different text based on how the user got to the page.

I.e.,
<cfif user comes from sitemap.cfm>
    Display this text
<cfelse>
    display this text
</cfif>
Can someone point me in the right direction?
解决方案
You want to look at the CGI environment variables, specifically HTTP_REFERER (and no, that isn't misspelled -- or, I should say, the name of the CGI variable is misspelled).

I believe the value of HTTP_REFERER will contain the entire URL, including the query string, so you'll have to parse it -- or perhaps use CONTAINS or findNoCase() in your <cfif> statement:
<cfif findNoCase("sitemap.cfm", cgi.HTTP_REFERER)>
    Display this text
<cfelse>
    display this text
</cfif>
It's important to note that the value of HTTP_REFERER will be empty if you're going from HTTP to HTTPS -- and vice-versa, I believe.
