But if you have custom headers that you want a client in a browser to be able to see, you need to add them to your CORS configurations ([CORS (Cross-Origin Resource Sharing)](cors.md)) using the parameter `expose_headers` documented in [Starlette's CORS docs](https://www.starlette.dev/middleware/#corsmiddleware).

You could also use `from starlette.requests import Request`.

    UnicodeEscaper e = (UnicodeEscaper) urlFormParameterEscaper();
    // Verify that these are the same escaper (as documented)
    assertThat(urlFormParameterEscaper()).isSameInstanceAs(e);

you dig right into the code, there are a few guidelines that we need
contributors to follow so that we can have a chance of keeping on top of
things.

Some of the ideas are documented in the [Maven Wiki][maven-wiki]
which might be interesting to read and for further discussion.

Getting Started

But if you have custom headers that you want a client in a browser to be able to see, you need to add them to your CORS configurations (read more in [CORS (Cross-Origin Resource Sharing)](../tutorial/cors.md)), using the parameter `expose_headers` documented in [Starlette's CORS docs](https://www.starlette.dev/middleware/#corsmiddleware)....

## Notes { #notes }

When you return a `Response` directly its data is not validated, converted (serialized), or documented automatically.

But you can still document it as described in [Additional Responses in OpenAPI](additional-responses.md).

    checkNotNull(cells);
    if (rowComparator != null || columnComparator != null) {
      /*
       * This sorting logic leads to a cellSet() ordering that may not be expected and that isn't
       * documented in the Javadoc. If a row Comparator is provided, cellSet() iterates across the
       * columns in the first row, the columns in the second row, etc. If a column Comparator is

Public properties are **stable properties**: they CANNOT be renamed or removed without notice.
While we normally deprecate the feature or behavior itself, changes to the property cannot happen in a minor release.
Public properties must be documented.
