Unable to redirect with content on Full Framework

[sanyappc]

HttpClient disposes HttpContent after request on full framework (not core):
Why does HttpClient dispose HttpContent?
Stop disposing of request content in HttpClient

But FlurlRequest.ProcessRedirectAsync tries to reuse disposed content for redirect request and this leads to CapturedJsonContent disposed exception

I'll look into this. Just so I can repro easily, what's the HTTP verb and status (3??) of the original (redirecting) call?

[sanyappc]

it's PUT with 301

Sorry to do this but I think I'm going to mark this a won't-fix. I looked into it and it would be quite an involved fix, I haven't heard about anyone else running into it, and as you noted it only affects people still on full Framework, which is becoming fewer and fewer in a .NET 6 world.

You've probably found a work-around by now, but I'd suggest either trying to recreate the content in the OnRedirect event (I'm honestly not sure it that'll work), or disable automatic redirects entirely and handle them manually. See #500.
