PingAccess

Release Notes

These release notes summarize the changes in current and previous PingAccess agent for Internet Information Services (IIS) updates. Updated July 11, 2024.

Version History

Version 1.5.0 – July 2024

Agent SDK for C version 1.4

  • If you use a Web + API application, the vnd-pi-resource-cache PingAccess agent protocol (PAAP) header now contains an additional path so Web + API applications can cache both cookie and authorization header token-types. For more information, see the Cache multiple token-types for Web + API applications entry in the PingAccess 8.1 release notes, and the agent.cache.defaultTokenType property on the IIS agent configuration page.

    Existing agent environments ignore the new vnd-pi-token-cache-oauth-ttl header and additional paths in the vnd-pi-resource-cache header.

    To see the performance boost, upgrade to PingAccess 8.1 and upgrade to the latest version of the IIS agent. Otherwise, continue to use an earlier agent version.

  • Configure the PingAccess agent for IIS to block requests that contain bad characters in the URI, query parameters, form parameters, or request body without having to reach out to PingAccess for a decision. Added eight new properties to the agent:

    1. agent.request.block.xss.characters

    2. agent.request.block.uri.characters

    3. agent.request.block.query.characters

    4. agent.request.block.form.characters

    5. agent.request.block.xss.http.status

    6. agent.request.block.uri.http.status

    7. agent.request.block.query.http.status

    8. agent.request.block.form.http.status

      Learn more in the IIS agent configuration page.

      For large scale or more complex blocking decisions, it’s best practice for the agent to reach out to PingAccess for a decision.

  • Added a new configuration option to give protected applications better reliability without giving up the ability to perform CRL checking when the server is available: the agent.engine.configuration.checkCertRevocation.bestEffort property.

This change provides better alignment between PingAccess, PingFederate, and PingAccess policy server CRL checking. Learn more in IIS agent configuration.
