## Symptoms

- Content Awareness blocks traffic with this log:

Reason: Content Awareness - Error: Received out of range HTTP 206 response (1003)

Action Reason: Blocking request as configured in engine settings of Content Awareness

Blade: Firewall

Product Family: Access

## Cause

In some scenarios (for example, during a PDF file download), the server responds with the HTTP 206 "Partial content" packet and sends the file in sections.

If the first file section is not the start of the file, then for security reasons the Security Gateway blocks this first section.
