Google App engine PHP post back problem

i have uploaded a php web application to google app engine , but all the POST bac开发者_StackOverflowk pages are open as a 'save as' without post backing the data ! ..

any one has a solution for this ? or a alternative for POST ?

Google app engine runs applications written in Python or Java, not PHP. You could work around it using Quercus (PHP runtime written in Java)
