RedirectHandler maintains `max_redirect` state across requests

[vpotter]

When using RedirectHandler for multiple requests without specifying custom options, we encounter an issue where the max_redirect counter is shared across all requests handled by a single RedirectHandler instance. This is problematic when downloading drive items using the Microsoft Graph API, which respond with a 302 Found redirect to a preauthenticated download URL.

After 5 successive downloads, the handler raises Too many redirects exception due to the shared counter reaching its default limit, effectively preventing further downloads.

Hi @vpotter
Thanks for your interest in kiota and for reporting this.
My Python is not great but to me it looks like:

• The request history should not be a field on the middleware handler, but rather a variable
• The decrement should not be made on the options field directly, but rather on a copied variable
• The retry handler might also be having the same issue.

Is this something you'd be willing to submit a pull request for?

While we wait for a resolution, are there any workarounds for this issue, in particular when using the msgraph SDK? We are blocked by this when doing file downloads for an archiving system.

not that I know off besides disabling the handler all together which is not going to workaround your issue here.
But a PR was started, see #258

@snorrea there is a workaround here
