We have an HTML form which is submitted via HTTPS. We've noticed that when the form is submitted on a home network, it seems to go through just fine. However, when the form is submitted on certain corporate networks, the data seems to disappear (the browser doesn't yield an error message but the POST data never hits our server).
We checked our SSL certificate installation at
http://www.digicert.com/help/ and everything checked out okay. The intermediate certificate is also installed correctly.
Since our SSL certificate was issued by Starfield Secure Certification Authority (a subsidiary of GoDaddy), which is a newer player on the SSL market, we're beginning to wonder if some older corporate firewalls are blocking these HTTP requests because they don't recognize the issuer. Is this possible? If so, is there any solution besides purchasing a certificate from a more recognized issuer (e.g. Verisign)?
GoDaddy offers the option to choose between GoDaddy and Starfield as the issuer. We chose Starfield to avoid the name 'GoDaddy' on our certificate, but would it help to switch the issuer to GoDaddy?
