htaccess的最后重定向太多了？

Question

尝试确定访问页面时只有最后一次重定向返回“Too Many Redirects”错误的原因。如果我在最后一个之后再添加，他们在访问页面时都会得到相同的错误。

Answer 1

您的上次重定向导致重定向循环错误/重定向错误太多。让我们看看为什么会这样：

RedirectMatch 301 ^/your-roof-as-a-selling-tool http://www.houstonroofingonline.com/your-roof-as-a-selling-tool.html

实际上，RedirectMatch的模式和目标路径是相同的。

模式：^ / your-roof-as-a-sell-tool *

目的地网址：http://www.houstonroofingonline.com/your-roof-as-a-selling-tool.html

当您请求qazxsw poi时，您的RedirectMatch会在第一轮将网址重定向到qazxsw poi。在第二轮中，example.com/your-roof-as-a-selling-tool匹配模式并重定向到自身。

要避免这种多重定向行为，您需要修复模式，使其与目标路径不匹配。只需在末尾添加正则表达式 http://www.houstonroofingonline.com/your-roof-as-a-selling-tool.html字符$，以便它只能匹配特定的uri http://www.houstonroofingonline.com/your-roof-as-a-selling-tool.html而不是end of string。

/your-roof-as-a-selling-tool
