# IIS

## 1.5.0 — 14<sup>th</sup> August

### Updates

#### Added configuration to skip blocking evaluation for internal requests

The IIS Agent now skips blocking evaluation for internal requests by default, aligning its behavior with other Traceable agents. A new configuration option `TRACEABLE_BLOCKING_SKIP_INTERNAL_REQUEST` has been exposed to control this behavior. When set to 1 (default), internal requests bypass blocking evaluation entirely. This prevents legitimate internal traffic from being inadvertently blocked by security policies.

***

Traceable’s IIS agent 1.3.1 provides the following:

### Updates

#### Libtraceable integration in 32-bit IIS agent

Adds support for IP-based inline blocking and sampling for customers.

#### Export logs from IIS agent

Adds support for exporting logs from the IIS agent.

#### Specify the environment in IIS agent configuration

#### Provide token to authenticate with TPA

Adds support for providing a token for authenticating with the Traceable Platform Agent (TPA).
