By default, in the APAHCE server, there is a URL http://blog.9cbs.net/tansf/, but if access http://blog.9cbs.net/tansf/, apache is not recognized (ie, you can't put T Change to T). Use the mod_speling module to solve this problem. When installing Apache, you should compile the mod_speling module, such as ./configure --prefix = / usr / local / apache2 --enable-so --enable-speling modifies httpd.con file, in this file, Plus Checkspelling on MOD_SPELING You can also automatically modify the wrong URL, the setting is the same, but starting checkspelling reduces the efficiency of Apache.
