cfhttp post authentication, troubleshooting tips

I'm trying to insert and update data via CFHTTP for a client. The problem is that I do not have access to the 3rd Party to find out what session variables are being passed. It's an .asp site. Authenticated via https I've charted out which parameters are sent via the form (hidden as well as displayed) and which are sent via the url. But things are not working. The form is not being updated and I'm not getting any errors. I was wondering what troubleshooting tips people had. I'm using <CFTRY> and <CFDUMP> But it's not catching everything (evidently). Thx

Gilbert, CFHTTP has a number of responses, have you out put them to see if anything of value shows up? <cfoutput> cfhttp.errorDetail: <cfdump var="#cfhttp.errorDetail#"> <br /> cfhttp.responseHeader: <cfdump var="#cfhttp.responseHeader#"> <br /> cfhttp.header: <cfdump var="#cfhttp.header#"> <br /> cfhttp.Filecontent: <cfdump var="#cfhttp.Filecontent#"> <br /> </cfoutput> BN ----- Excess quoted text cut - see Original Post for more -----
