Change User-Agent programatically

[David Quon]

Is it possible to change the Couchbase Lite User-Agent programmatically?  For example it would be helpful to be able to distinguish the difference between clients on different iOS versions.

+1 to this.  In fact, we just had the same thought about the user-agent while troubleshooting a sync issue with multiple devices behind a NAT.  That or another header that could be set on every request from the client would give some extra routing/blocking control in nginx as well.

You mean for collecting metrics of your app's users?

The user-agent is a hardcoded string, but you can change it by editing the source code :)

@interface CBLReplication : NSObject

/** Extra HTTP headers to send in all requests to the remote server.

    Should map strings (header names) to strings. */

@property (nonatomic, copy) NSDictionary* headers;

Not to collect metrics but mainly as a workaround for this issue:

For example we could redirect all traffic for iOS 8 CBL traffic to use TLS v1.0 and all other traffic to use TLSv1.2 based on the User-Agent.
