ISAPI_Rewrite is a Microsoft IIS compatible URL rewriter that works similar to Apache's .htaccess mod_rewrite. Designed to boost search engine optimization, it enables users to secure their servers, halt hotlinking, and offers reverse proxy for server content.
One of the top features of ISAPI_Rewrite is that it uses the same syntax and behavior as Apache mod_rewrite. This allows for seamless migration of configurations by copying .htaccess files. Additionally, the software supports regular expressions for flexible and powerful configurations. The pure C++ code is extremely fast, durable, and highly scalable, making it suitable for any size server environment.
ISAPI_Rewrite also offers distributed configurations, with options for global server level, virtual host (web site) level, and directory level .htaccess files with real-time monitoring. This feature ensures isolation as user-level configuration only affects the local user environment, making it an ideal solution for web hosting providers.
Some top usage examples of ISAPI_Rewrite include search engine optimization, proxying content between servers, preventing content leeching, blocking specific hosts or robots, content negotiation for serving different files based on language or browser, and load balancing emulation for web clusters.
ISAPI_Rewrite provides a comprehensive list of supported Apache .htaccess directives such as AccessFileName, AllowOverride, ErrorLog, LogLevel, RewriteEngine, RewriteRule, RewriteCond, RewriteBase, RewriteMap, RewriteLog, RewriteLogLevel, RewriteOptions, and RewriteLock. Users can also find additional examples in the software documentation and Apache online documentation or script archives. Most Apache examples can run with ISAPI_Rewrite without modification.
