In some cases, I need to get the raw request header

[L018]

Hi,

I find that all request's headers had do a casefold transform. I know that's right. But I think we should keep save raw headers instead of drop it. I haven't find any property or function to get it yet. In web security, I need to find something from the raw request that is not the same as the real human request.

I know we can add a raw_headers property to solve it. But i think you have a better idea.

This is something I was toying with the idea of adding into the streaming branch that will be merged in early 2021. Currently it reads to a buffer and then drains. The thought was to add a raw HTTP request object to store a cache of the bytes received on the request object. There might be some memory concerns here, so I do not think it should be enabled by default. But there are some uses for this.

This would be the entire object. As for just the raw headers? That is also worth consideration. But, again this would likely be an opt-in feature.

Yes, it is shouldn't be enabled by default. But I think request.body maybe a bit repetitive if we use a raw HTTP request object.

I think we could at least cache a raw version of the HTTP header. It should be small enough to always fit into memory.
