As the input stream passes through each process it is altered in whatever way sed is commanded to alter it by. When sed commands are chained together, each sed command processes the input stream in turn. Multiple sed instructions can be used to process the same input stream multiple times. Sed is a command line stream editor that can process an input stream on the fly. I had guessed that WordPress had been altering request URLs before my custom directives got to play with them but it wasn’t until I read the above quote from that I knew what was happening for sure. My custom rewrite rules didn’t always work. htaccess file are supposed to block known query string exploits and SQL injection exploits. ![]() mod_rewrite uses a slightly altered form of regular expressions to match URL patterns and – when a requested URL matches one of those patterns – to rewrite the requested URL or block access to it, as directed.įor example, a rewrite directive to check for URLs that contain the directory “script” which then rewrites the URL without the “script” directory would look like this, Options +FollowSymlinks One of the Apache modules (plugins) that lets requested URLs be filtered and rewritten is called mod_rewrite. htaccess files to see whether access to the requested file or directory is blocked it checks whether directory browsing is enabled it checks whether a URL should be rewritten and it checks for any number of directives that might change the way a request is handled. Requests to view directories are treated the same way. htaccess file in every directory along the path to the requested file before it serves the requested file. Whenever Apache receives a request to view a file, Apache reads every. Each directive is read and processed from the top of the file to the bottom of the file, successively. htaccess and processes any directives that are in it. htaccess works in the same way as any other Unix based configuration file: the server (Apache) reads. Correct me if I’m wrong with any of this. I’ve included it only as proof that I know a little about the subject. (Note: you may also see plugins using the rewrite_rules hook, but this is deprecated).ĭon’t worry if that’s gone over your head. htaccess, including the surrounding section. ![]() This function also has a filter, mod_rewrite_rules, which will pass functions the string of all the rules to be written out to. Mod_rewrite_rules() is the function that takes the array generated by rewrite_rules() and actually turns it into a set of rewrite rules for the. Here’s an extract from the WP_Rewrite class reference page this extract covers the mod_rewrite_rules() function: WordPress has a class called WP_Rewrite which is used to give any URL a pretty appearance when WordPress s are configured for pretty links. I figured this out a few days ago but at the time I was unsure about why this is the case. It turns out that custom rewrite rules must be placed before the WordPress rewrite rules in. ![]() As it happens, my rewrite directives didn’t completely work in all circumstances. ![]() Mostly, those rules are designed to stop bots and hackers from using query string exploits to do nasty little things to my blogs. htaccess rules to block requests to visit pages and to block requests to directly call scripts in WordPress directories when the requests look malicious. The last few days have highlighted a gap in my knowledge of the WordPress platform.
