[Cache] broaden query-string-sort troubleshooting to order-sensitive apps (Oracle EBS)

[ngayerie]

Summary

Broaden the Query String Sort troubleshooting section to cover enterprise applications with order-sensitive request handling, using Oracle E-Business Suite (EBS) as a confirmed example.

Motivation

The current page documents WordPress admin as the primary example of Query String Sort breaking applications. In practice, the same class of issue affects enterprise applications that use query parameters for session validation, CSRF protection, or request signing — Oracle E-Business Suite in particular. Customers searching for the specific "Insufficient Privileges" error EBS returns don't currently find a match on this page.

Changes

• Rename the "Unexpected behavior with WordPress admin pages" section to "Unexpected behavior with order-sensitive applications" to reflect the broader class of issue.
• Add one sentence to the intro connecting WordPress and enterprise apps.
• Add a new ### Enterprise applications with order-sensitive request handling subsection between the existing "Identify the problem" (WordPress walkthrough) and "Respond to the issue" (generic fix guidance). The subsection names Oracle EBS explicitly, shows the exact error string, lists other categories that may be affected (signed URLs, CSRF-hashed parameters, SAP/PeopleSoft), and refers the reader to the existing fix guidance.

No changes to the existing WordPress walkthrough or fix guidance.

Notes

• The H2 anchor changes from #unexpected-behavior-with-wordpress-admin-pages to #unexpected-behavior-with-order-sensitive-applications. Happy to add a redirect if the docs team prefers.
• Grounded in a real customer support case; case details are omitted from public docs as expected.
