301重定向：原网页或内容被永久性的搬迁到他处。
Apache的话，设置.htaccess文件，网上教程很多。 Nginx同理分析。301重定向常用来将将老域名指代的东西重新指向新的网页内容， 和CNAME不同，301重定向是不会对原网站的流量排名、权重等造成不良影响的，基本上不会对SEO有什么影响。 GMTYDetect languageAfrikaansAlbanianAmharicArabicArmenianAzerbaijaniBasqueBelarusianBengaliBosnianBulgarianCatalanCebuanoChichewaChinese (Simplified)Chinese (Traditional)CorsicanCroatianCzechDanishDutchEnglishEsperantoEstonianFilipinoFinnishFrenchFrisianGalicianGeorgianGermanGreekGujaratiHaitian CreoleHausaHawaiianHebrewHindiHmongHungarianIcelandicIgboIndonesianIrishItalianJapaneseJavaneseKannadaKazakhKhmerKoreanKurdishKyrgyzLaoLatinLatvianLithuanianLuxembourgishMacedonianMalagasyMalayMalayalamMalteseMaoriMarathiMongolianMyanmar (Burmese)NepaliNorwegianPashtoPersianPolishPortuguesePunjabiRomanianRussianSamoanScots GaelicSerbianSesothoShonaSindhiSinhalaSlovakSlovenianSomaliSpanishSundaneseSwahiliSwedishTajikTamilTeluguThaiTurkishUkrainianUrduUzbekVietnameseWelshXhosaYiddishYorubaZuluAfrikaansAlbanianAmharicArabicArmenianAzerbaijaniBasqueBelarusianBengaliBosnianBulgarianCatalanCebuanoChichewaChinese (Simplified)Chinese (Traditional)CorsicanCroatianCzechDanishDutchEnglishEsperantoEstonianFilipinoFinnishFrenchFrisianGalicianGeorgianGermanGreekGujaratiHaitian CreoleHausaHawaiianHebrewHindiHmongHungarianIcelandicIgboIndonesianIrishItalianJapaneseJavaneseKannadaKazakhKhmerKoreanKurdishKyrgyzLaoLatinLatvianLithuanianLuxembourgishMacedonianMalagasyMalayMalayalamMalteseMaoriMarathiMongolianMyanmar (Burmese)NepaliNorwegianPashtoPersianPolishPortuguesePunjabiRomanianRussianSamoanScots GaelicSerbianSesothoShonaSindhiSinhalaSlovakSlovenianSomaliSpanishSundaneseSwahiliSwedishTajikTamilTeluguThaiTurkishUkrainianUrduUzbekVietnameseWelshXhosaYiddishYorubaZuluText-to-speech function is limited to 200 charactersOptions : History : Feedback : DonateClose |
ISAPI Rewrite 3 几个常用 301 重定向规则
ISAPI Rewrite 不同版本的规则略有差别，这个帮助文件中有较详细的规则参考，附几个常用的写法：
下面的301规则仅适用于 ISAPI Rewrite 3，其他版本请勿使用！
1、将“”301重定向到“www.”
RewriteEngine on
RewriteCond %{HTTPS} (on)?
RewriteCond %{HTTP:Host} ^(?!www.)(.+)$ [NC]
RewriteCond %{REQUEST_URI} (.+)
RewriteRule .? http(?%1s)://www.%2%3 [R=301,L]
2、301重定向到另一个域名
RewriteCond %{HTTP:Host} ^www.
RewriteRule (.*) http://www. [NC,R=301]
3、301重定向单个页面
RewriteRule ^/oldpage.htm$ http://www. [R=301,L]
将以上代复制到记事本内并保存为.htaccess文件上传到你的空间WEB下即可！
