• Issue: Caching configurations #10957
• Type: Suggestions / Documentation
• Summary: Added documentation for IDP cache configuration (idp_cache_by_name) that affects how quickly IDP configuration changes are reflected between APIM and IS carbon portals in integrated deployments. This addresses the 15-minute delay mentioned in the issue and provides reference to WSO2 IS documentation for detailed cache layer information.
• Style Scope Verification: Microsoft Style Guidelines have been applied ONLY to newly added content without modifying existing content style.
• Verification: Documentation builds successfully (pre-existing mkdocs.yml configuration warnings unrelated to this change)
