For example, these should match: "/assets" and "/assets/12345", but these shouldn't match: "/assets" and "/assets_exist".

The previous code didn't actually send the response, so the caller was stuck until the timeout (100 seconds).

- MemoryBuffer isn't seekable, so we can't log it. Log the string instead.
- Handle compressed streams
- Don't attempt to dump binary data. Either don't log it at all (if we know it's binary), or at least convert non-ASCII characters to ASCII.
- Log responses to HTTP requests
- Use the same log prefix for all of these log messages ("[LOGHTTP]"), to make them easy to see at a glance
- Increased the snippet length to 200 (80 doesn't show enough), and add "..." only if the message was actually truncated

long poll and other 'poll' types

This shows the number pf poll responses queued for processing.
|
|
Involved some restructuring to allow regression tests to dequeue inventory requests and perform poll responses synchronously rather than async
|
|
console rather than log as warning
The problem with logging at warn is that these aren't actually warnings, and so are false positives to scripts that monitor for problems.
Ideally, log4net would have a separate "status" logging level, but currently we will compromise by putting them to console, as they are user-oriented

* Add an IsBlocked(string Key) method so it can be used more generically. (think.. if we want to rate limit login failures, we could have a call in the Login Service to IsBlocked(uuid.ToString()) and ignore the connection if it returns true, if IsBlocked returns false, we could run the login information and if the login fails we could run the Process method to count the login failures.

* Break out common BasicDOSProtector code into separate class.
|
|
HTTP Server handlers. XMLRPC Handler, GenericHttpHandler and <Various>StreamHandler
* Applied the XmlRpcBasicDOSProtector.cs to the login service as both an example, and good practice.
* Applied the BaseStreamHandlerBasicDOSProtector.cs to the friends service as an example of the DOS Protector on StreamHandlers
* Added CircularBuffer, used for CPU and Memory friendly rate monitoring.
* DosProtector has 2 states, 1. Just Check for blocked users and check general velocity, 2. Track velocity per user, It only jumps to 2 if it's getting a lot of requests, and state 1 is about as resource friendly as if it wasn't even there.

When Melanie added the web fetch inventory throttle to core, she made the long poll requests (EQs) effectively be handled on an active loop. All those requests, if they existed, were being constantly dequeued, checked for events (which most often they didn't have), and requeued again. This was an active loop thread on a 100ms cycle!
This fixes the issue. Now the inventory requests, if they aren't ready to be served, are placed directly back in the queue, but the long poll requests aren't placed there until there are events ready to be sent or timeout has been reached.
This puts the LongPollServiceWatcherThread back to 1sec cycle, as it was before.

handlers.
This adds explicit cap poll handler supporting to the Caps classes rather than relying on callers to do the complicated coding.
Other refactoring was required to get logic into the right places to support this.

This happens in HEAD handlers.

to print various counts of capability invocation by user and by cap
This currently prints caps requests received and handled, so that overload of received compared to handled or deadlock can be detected.
This involves making BaseStreamHandler and BaseOutputStream record the ints, which means inheritors should subclass ProcessRequest() instead of Handle()
However, existing inheriting classes overriding Handle() will still work, albeit without stats recording.
"show caps" becomes "show caps list" to disambiguate between show caps commands
