I'm using the outbound SMS sending function, and have configured my server script (PHP) to respond to GET parameters from IBF, as well as (for troubleshooting and testing). It works fine, generally. However, I'm noticing two issues:

#1: An SMS message occasionally gets lost. Is there a throttling mechanism in play? Or is there a safety or abuse-prevention mechanism that throttles or ignores duplicate texts (my testing data is generally identical, and would tend to produce perhaps a dozen perfectly identical texts (same to: number, same from: number, same content) in quick succession).

#2: I  occasionally get a random SMS message… possibly one of the ones that got lost… or one that got throttled. Has this been documented? There is a third possibility...

#3: (I've never seen anything like this before). When testing and typing a string into my browser for testing, such as the following:

http://mysite.com/myscript.php?from_number=+11234567890&to_number=+11234567890&message_text=I%20Want%20a%20Free%20iPad

I am noticing that whenever my browser suggests a URL endpoint from my browser history, I receive a sudden flurry of text messages on my phone… AT EACH POINT WHERE MY BROWSER AUTO-SUGGESTS A URL, and every 3 seconds until I move the cursor out of the address bar. Clearly, my browser is pre-fetching, or querying the site for a change date, checking for a cached version, etc. What's happening here… does anyone know the specific underlying mechanism??? I've never actually NOTICED this phenomenon in any other context. I live tests lots of scripts like this, and if this was a widespread phenomenon, I'd have ruined my career by now: repeating SQL loads, re-running scripts that should only run once, or at the wrong time.

Two cents? Random musings? For what it's worth, I realize this is, of course, a client-side issue. I'm browsing with Safari on OSX.
