3xx Redirection

HTTP 305 Use Proxy

The requested resource must be accessed through the proxy specified in the Location header. This status code is deprecated due to security concerns with in-band proxy configuration.

Common Causes

  • Server requiring access through a specific proxy
  • Legacy network configuration enforcing proxy usage
  • Deprecated — rarely seen in modern systems

How to Fix

  1. 1Configure the client to use the specified proxy
  2. 2This status is deprecated — consider updating the server
  3. 3Use network-level proxy configuration instead

Example

HTTP 305 Use Proxy
GET /resource HTTP/1.1

→ 305 Use Proxy
→ Location: http://proxy.example.com:8080/
