Need recommendation for HTTP-Port for Froms and Reports

Hi all,

I need your recommendation and experince for HTTP-Port for Froms and Reports. I read in "What HTTP Ports Can Be Used To Connect To Forms and Reports 11g Services ? [ID 1411024.1]"

that for prodution environment ist recomended to use OHS/Web Cache Ports (and not ports of WLS_FORMS or WLS_REPORTS).

What is your experince and why for production is better to use OHS/Web Cache ports?

Thanks in advance,

Moh
