GET floods with Drawbridge

[kenrestivo]

I'm not sure where this could be coming from-- repl-y, lein, drawbridge, nrepl, or something else-- but since the decision when to send these appears to be made by repl-y, I'll post this here and hope for the best.

When doing a very simple compojure hello world following the drawbridge README, and then connecting via:

lein repl :connect http://localhost:8080/repl

Everything seems to work, but a packet sniff shows that the server is getting pummeled by empty GET requests to that URL, every 8ms.

The GETs seem identical, and take this form:

GET /repl HTTP/1.1
Connection: close
accept-encoding: gzip, deflate
cookie: ring-session=e868f195-cc61-4e4b-9dc0-619446e17ffa
Content-Length: 0
Host: localhost:8080
User-Agent: Apache-HttpClient/4.2.2 (java 1.5)

HTTP/1.1 200 OK
Date: Mon, 28 Jan 2013 00:53:17 GMT
Content-Type: application/json;charset=ISO-8859-1
Connection: close
Server: Jetty(7.6.1.v20120215)

There are POSTs amongst this haystack that have acutal forms and their evaluation results, so it's working. But that's a lot of SPAM packets, apparently just no-ops. Every 8ms seems a bit excessive.

This is using Leiningen 2.0.0-RC2 on Java 1.7.0_03 OpenJDK 64-Bit Server VM, and drawbridge 0.0.6.

I'm going to close this based on our discussion in nrepl/drawbridge#10 - REPLy's 100ms timeout on the recv should mean it only calls recv more often than that if responses are actually coming back before the timeout expires.
