Thanks for update will inform

[bhagyshricompany]

Issue needs mechanism to parse the scheme for incoming url.
So will update on this once done.

@bhagyshricompany, WsgiRequest appears to handle scheme correctly with urllib.parse.urlparse

#...
from urllib.parse import ParseResult, urlparse, unquote_to_bytes

class WsgiRequest:

    def __init__(self,
                 func_req: HttpRequest,
                 func_ctx: Optional[Context] = None):
        url: ParseResult = urlparse(func_req.url)
#...
        self.wsgi_url_scheme = url.scheme
