HTTPUpgrade send headers with specified capitalization

[Fangliding]

昨晚上看到就知道怎么搞了 感觉没必要就没动 没想到第二天起来看到还写了个这么复杂的玩意的
个人觉得还是有一点点必要维持可读性的（）

好像revert了不该revert的东西 等一下下（）

thank you, in general i agree. i did not intend to write such a complex code originally.

i did not know it's possible to insert into the map directly, that's cool. but there is now another issue. if i have a config like this:

        "httpupgradeSettings": {
          "path": "/hu",
          "headers": {
            "host": "example.com"
          }
        }

this version of xray will send two host headers Host and host

this may seem like a minor issue, but i think existing configs like this could break. i think it can be fixed using an explicit hasHostHeader variable...

about simplicity... originally i wanted to remove all http.Request. in my mind net/http is very complex to understand, so this is what i was trying to remove here. if no users report bugs in the next version of xray, i can open a PR to restore the state of commit 097990926fb6ccd3c50c2bd798ef856d9208fb7f in #3427. this is also simpler, what do you think?

It has a pre-check, I just need 2 lines to fix it.

No need. I'm just saying it is unnecessary to worry about the capitalization of the header. If there's a simple way to implement it, let's just keep it

Thanks @Fangliding @mmmray

also @Fangliding one thing to share :

IRGFW throttles and blocks all unknown sni's it kinda went MAD in that sense ( Cant understand --> block ) - and you are overestimating abilities of current IRGFW in fingerprinting notls connections

Still i understand XRAY is not specific to a single country its for everyone and you want something that everyone can use - but its good to be less-fingerprintable with notls
