Notes
The 2 forms on top of this page are live.
Fill in either form and then click "Calc".
Underneath will be displayed the string that was sent to the server and the status code and results that were received from the server.
"Success" will be set to "true" if the conversion was successful or "false" if it was not.
If "success==false" an additional field called "errormessage" will be set as follows:
{
"success" : false,
"errormessage" : "inputdls(): Range '233' is invalid"
}
Below the status lines, the parsed results and raw geojson string are displayed.
Both http:// and https:// are active.
An account and a purchase are required.
If purchase for evaluation is difficult, we can setup an evaluation account for you.
You can also send the user name and password in the url string
Encrypted -- SECURE

Unencrypted -- EASY

Sending the username and password unencrypted in the url string may seem a bit "unsecure", but is very simple to code up in every computer language, and to do so without any 3rd party libraries.
Cross Site Scripting
Modern Web Browsers do not allow "Cross Domain Scripting".
Use a web proxy to incorporate GeoJSON results from legallandconverter.com's server into webpages from your server.
