continous feed clean up (phonegap specific?)

[Seung Chan Lim]

I have a question about continuous feeds (changes feed for example) in phonegap applications.

I'm using XMLHttpRequest object to keep alive a socket connection to "http://lite.couchbase." I get a callback everytime my readystate changes.

What I've noticed is that the new changes get appended to the http body. Now I could imagine this could grow quite large at times.

Is there any best practice for this? I suppose I could periodically disconnect re-establish a new connection (thus freeing up the memory) if I deem the buffer has grown too large, but I wanted to check if there are simpler/smarter ways of dealing with this.

Interesting — that must just be a side effect of the way the XMLHTTPRequest object works.

I don't know. (Maybe JChris does?) You might ask around the CouchDB community, as this is something CouchApps would run into as well.

That sounds reasonable. You could also switch to the 'longpoll' feed, which will close the response after sending one update, after which you send another request.
