 # Security settings for Multi-User Transcription Server
 # Compatible with both mod_php and php-fpm
 
+# IMPORTANT: For Server-Sent Events (SSE) to work with php-fpm, you MUST configure
+# Apache's ProxyTimeout in your virtual host configuration. See apache-sse-config.conf
+# for the required settings. Without this, Apache will timeout SSE connections after
+# 30-60 seconds with a 504 Gateway Timeout error.

 # Deny access to config file directly (if accessed via URL)
 <Files "config.php">
