Which Version of ISAPI_Rewrite Is Installed on My Windows Hosting?
ISAPI_Rewrite is installed on all Fast2host Windows hosting servers. It provides Apache‑style URL rewriting for IIS, allowing clean URLs, redirects, and SEO‑friendly structures.
Modern Windows servers now use ISAPI_Rewrite 3 as the standard version, while older servers may still run version 2 for legacy compatibility.
ISAPI_Rewrite 3 (Current Standard)
Most Fast2host Windows servers now run ISAPI_Rewrite 3. This version uses .htaccess files, similar to Linux hosting.
- Place your rewrite rules in: wwwroot/.htaccess
- Supports Apache‑style syntax
- More powerful and flexible than version 2

ISAPI_Rewrite 2 (Legacy Servers)
Some older servers still run ISAPI_Rewrite 2. This version uses an httpd.ini file instead of .htaccess.
- Place your rewrite rules in: wwwroot/httpd.ini
- Uses a different syntax from version 3
- Maintained for legacy application compatibility
