mod_http_oauth2: Fix treatment of 'redirect_uri' parameter in code flow
It's optional and the one stored in the client registration should
really be used instead. RFC 6749 says an URI provided as parameter MUST
be validated against the stored one but does not say how.
Given that the client needs their secret to proceed, it seems fine to
leave this for later.

16 First, download and add the module to `module_enabled`. Then you can |
| 1842 | 17 decide on what policy you want to have. |
| 18 | |
| 19 Requiring ciphers with forward secrecy is the most simple to set up. | |
| 20 | |
| 21 ``` lua | |
| 22 tls_policy = "FS" -- allow only ciphers that enable forward secrecy | |
| 23 ``` | |
| 24 | |
| 25 A more complicated example: | |
| 26 | |
| 27 ``` lua | |
| 28 tls_policy = { | |
| 29 c2s = { | |
| 30 encryption = "AES"; -- Require AES (or AESGCM) encryption | |
| 31 protocol = "TLSv1.2"; -- and TLSv1.2 | |
| 32 bits = 128; -- and at least 128 bits (FIXME: remember what this meant) | |
| 33 } | |
| 34 s2s = { | |
| 35 cipher = "AESGCM"; -- Require AESGCM ciphers | |
| 36 protocol = "TLSv1.[12]"; -- and TLSv1.1 or 1.2 | |
| 37 authentication = "RSA"; -- with RSA authentication | |
| 38 }; | |
| 39 } | |
| 40 ``` | |
| 41 | |
| 42 # Compatibility | |
| 43 | |
| 44 Requires LuaSec 0.5 | |
