Why POST call doesn't work within AEM?



@For security reasons I would like to use POST call in passing the data from one AEM page to another AEM page. When I do a POST call, I'm getting the below error. What is the exact reason behind this and why it is not allowed to do POST call within AEM? Any other work around from front-end? Please let me know.

Status 500
