# PingAccess Agent for IIS 1.4.3 (December 2020)

## Agent SDK for C compatibility

Info

Compatible with the Agent SDK for C version 1.3.

## Disable IIS caching only when modifying response

Improved PAA-202

Updated the agent to only disable IIS caching when the agent modifies the response. This preserves performance while mitigating an IIS session swapping vulnerability.
