The answer is dependent on the GIS software; please edit the question to specify the software (with version)

Maybe you should check a forum associated with the device. As it stands, there is no GIS component to this question.

comment How to get the Shape.STLength() value from JSON
You can write your own length function to iterate over the array of array of ordinates, or you can include the length on the query that generates the JSON.

comment How do I enumerate the messages in arcpy.GetMessages()?
Splitting by newline and walking the array members springs to mind. Skip the last if it's empty.

Back in the old days we called this CREATELABELS/IDENTITY/IDENTITY, but Dale now calls this Spaghetti and Meatballs analysis there was a follow-on blog post as well

That's what ST_DWithin is for. A little due diligence goes a long way.

This query cannot use a spatial index (since it forces a full table scan). Performance is therefore dependent on the number of features in the table.

comment How to force the urlUtils proxy perform only POST requests
urlUtils doesn't, because that's not its purpose. The JSAPI does, because I use it. You haven't provided a query, so no one can show you how to specify a POST method.

A geography cast is likely to fail with -104.96 latitude.

You need to reload your tables in X,Y order, either as decimal degrees with a geography type, or in meters in an equal area projection as geometry. Editing the question to give more details about the PostgreSQL/PostGIS release (and removing cartodb from the tags) and how the table has been constructed would allow for more details.

It's not radians (in which case 500 would wrap the globe 80 times), but Cartesian degrees which still covers the globe.

If you're using GEOMETRY (not GEOGRAPHY), the third parameter is a distance in the coordinate reference of the table (which apparently is degrees). 500 linear degrees goes a long way, even from a location at 105 degrees south (coordinates are in X,Y order, which is lon,lat)

comment How to force the urlUtils proxy perform only POST requests
I think you're barking up the wrong tree. The web requests themselves determine whether a GET or POST is submitted, not the proxy rule. In esri.request this means specifying usePost:true in the request JSON. On dojo forms it means using form.method = "post". Without the relevant code it's impossible to answer beyond 'You can't.'
