ISAPI_Rewrite x64 is a regular-expression URL rewriting engine for Microsoft IIS. It processes incoming requests using rules that can map addresses to application resources, support custom URL schemes, and create host-header-based sites. Its Apache mod_rewrite-compatible syntax can help administrators migrate existing rules, including .htaccess configurations. Rules can be managed globally, per website, or at directory level, with user-level isolation for shared hosting environments.

ISAPI_Rewrite x64 is a URL rewriting engine for Microsoft Internet Information Services (IIS), intended for administrators and web hosting providers who need to control how incoming web addresses are handled. It uses regular-expression rules to map requested URLs to different resources or application paths, and can support custom URL schemes and host-header-based sites. As an ISAPI filter, it works within IIS rather than requiring a separate web server.
Its rule syntax and behavior are designed to be compatible with Apache mod_rewrite. This can make it easier to transfer existing rewrite configurations, including rules stored in .htaccess files, when moving sites to IIS. Administrators can use regular expressions to match parts of a request and define how matching addresses should be processed. This is useful for presenting clean or consistent URLs while directing requests to the appropriate content behind the scenes.
Configuration can be applied at several scopes: globally for the server, for an individual website, or within directories using .htaccess files. Distributed configuration lets a hosting provider set shared server rules while allowing site owners to maintain rules for their own environments. Real-time monitoring of directory-level configuration files helps changes take effect without relying on manual file copying. User-level isolation keeps an individual user's settings confined to that user's environment.
The filter is implemented in C and C++, with an emphasis on processing requests quickly and handling scalable IIS deployments. Administrators can use it to define host-based site behavior, maintain URL rules across multiple hosted websites, and adapt Apache-style rewrite configurations for Microsoft servers. Its scope and isolation options are particularly relevant where many sites share one IIS installation but need separate rewrite policies.
ISAPI_Rewrite x64 is trialware for 64-bit Windows environments. It is intended for use with IIS and is suited to server administration rather than general desktop URL management. The supplied platform information includes Windows XP and 64-bit editions of Windows Vista, Windows 7, Windows 8, and Windows 10; specific IIS requirements depend on the server environment. Its rule-based approach is most useful to administrators familiar with web server configuration and regular expressions.
