error POSTing quiz data to own server (through cgi)

Hi!

We're pretty new to Lectora, so this might be old hat to some of you. Here is our issue in a nutshell:

We are trying to post quiz data to our own server (no SCORM or LMS). Sometimes the data makes it, other times there is an "internal server error 500" on the server receiving the data. If we run the same title 10 times in a row, maybe 8 times the data goes through, twice we see the "internal server error 500".

Additional detail:

Different sets of titles run on different domains. The data for the different sets of titles need to be stored in different data bases. Because the URL to send the quiz data to our server(s) must be hard coded within the title, we have one URL (form handler) that acts like a "traffic cop" to receive the data from any title (from any domain). The information in one of the title's variables (now a form field) indicates the domain associated with the title, so the "traffic cop" then sends (posts) a copy of the data to another URL (form handler) to read the data (form fields) and store the needed pieces of data in a data base for that domain.

So the flow of data looks like this:

title (domain A) --> "traffic cop" (domain X) --> data storage (domain B) , where A may or may not = B, but A != X and B !=X. (Server A and server X are different servers.)

The error occurs when the trivantis.js file POSTS the data to the URL specified in the title; i.e., from the title (domain A) to the "traffic cop" (domain X).

Our thoughts tend to cross domain issues, but since it is successful much of the time, we're not sure.

Any help insight would be appreciated.

(If it matters, we're using ColdFusion on the cgi side.)
