The people who wrote the specs for SAP OCI should be hanged by rusty barbed wire while being tickled by krusty the clown.
Which one of these stinky hobbits thought it was a great idea to require a (catalog) server to handle a POST request by sending back an HTML form which has to execute a POST request immediately by JavaScript on load?
Why not fucking respond with the actual god damn fucking data?
Some "senior" (read "senile") software "engineer" has to get decapitated.

Quote from the specification (OCI Function: VALIDATE, section 2.3.2):
"The product catalog replies with an HTML page that contains a form with the productdata in OCI format. [...] The HTML page may not contain any visible elements ([...]). The form must be sent automatically by JavaScript after the page has been loaded."

The only thing that should get sent after loading would be these people's asses to hell after my minigun has finished loading.

SAP is the kind of company who earns a huge junk of money from utter, stinking, filthy crap and they like to piss in their customers' "müesli".
