Motivation & Context

AgentWithRAG_Step02_CustomVectorStoreRAG downloads two pages from the main branch of MicrosoftDocs/semantic-kernel-docs. The pages were removed from main on October 23, so both URLs return 404 and the sample stops at the first download.

Description & Review Guide

• What are the major changes? The two URLs point to commit caf5bacd of MicrosoftDocs/semantic-kernel-docs, the last commit of main that has the pages.
• What is the impact of these changes? The sample downloads the same pages as before. A fixed commit also keeps working if the pages move again.
• What do you want reviewers to focus on? The pinned commit: it keeps the content that the questions of the sample were written for.

Tested:

• Before: the sample stops at the first download with HttpRequestException: Response status code does not indicate success: 404 (Not Found).
• After: both pinned URLs return 200, and the sample gets past both downloads.
