Any smart idea on how to intercept and modify cookies from a remote server response before passing them to the Cookies feature plugin? At work, we are communicating with an external service that requires cookies but that sends the Expires cookie in an incorrect format (i.e. localised, German weekday abbreviations that are only 2 chars long). The ktor-client module in our codebase subsequently throws an exception at https://github.com/ktorio/ktor/blob/68eef1948ce4c8c11dae794588f8d063afb67d0b/ktor-http/common/src/io/ktor/http/DateUtils.kt#L20 blocking further development. The communications partner is an enterprise-grade provider, so negotiating with them to just abide by the f*ing standards is not an option, I'm afraid. (Although it's sad that a company like them doesn't care for standards in the first place, but that's totally not my point here.)

Currently, our solution is copying the entire sourcecode from the Cookies module and modyfing the content before passing them to fun String.fromHttpToGmtDate. But arguably, this is even a more horrible solution than SAP not getting their stuff right.

The right solution would be to intercept the response pipeline and fix broken header instead of rewriting features. However currently not enough public API to do that (to create a new client call with replaced headers). Could you please file an issue and describe your usecase?

We just decided to fix public API to make it possible.

🤩 Thank you, will do!
