Quoted-string Basic realm ctx according to rfc7235

[ArfyFR]

Hi,

I faced some problems with 401 message and an Android client.

It yelded because in the WWW-Authenticate header the Basic ream= wasn't surrouned by ""

In the https://tools.ietf.org/html/rfc7235 it is written that

• Authentication parameters are name=value pairs
• and "auth-param = token BWS "=" BWS ( token / quoted-string )"
• and "For historical reasons, a sender MUST only generate the quoted-string syntax. Recipients might have to support both token and quoted-string syntax for maximum interoperability with existing clients that have been accepting both notations for a long time."

After my modification, the Android worked again (and iOs and PC clients faicing the 401 still worked ;) )

BR, Arfy
