Summary of Changes
Hello @gaby, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request focuses on improving the accuracy and clarity of the CORS middleware documentation and its internal comments. It addresses several inaccuracies related to the ExposeHeaders type, the correct usage of AllowOrigins with credentials, and the precise behavior of the Vary header, while also refining a code example for better understanding.
Highlights
- Documentation Accuracy: Corrected the documented type for
ExposeHeadersin the CORS configuration table fromstringto[]stringto accurately reflect its usage as a slice of strings. - Code Example Clarity: Updated the
AllowOriginscode example for subdomain matching to correctly use a string slice ([]string) instead of a single string, aligning with the expected configuration. - CORS Behavior Clarification: Enhanced the explanation of the
Varyheader's role in CORS, detailing its behavior for both simple and preflight requests to improve caching understanding and accuracy. - Security Comment Refinement: Clarified the internal comment for
AllowCredentialsinconfig.goto explicitly state that the wildcard origin ("*") cannot be used with credentials, rather than implyingAllowOriginsitself cannot betrue.

Code Review
This pull request provides several documentation and comment fixes for the CORS middleware. The changes clarify the use of wildcards with credentials, correct the type for ExposeHeaders in the documentation, update an example to use a slice for AllowOrigins, and improve the description of the Vary header. The changes are generally good and improve clarity. I've pointed out one minor inaccuracy in the updated Vary header description for further improvement.
