I am developing a Python-Django web app. It lets people visiting my site to embed an already created poll widget to their sites. The problem is when a visitor embeds a poll in a site that has much traffic - so that many people vote on the poll at the same time. It can lead to overload and I don't know how to handle that.
My site is hosted on shared hosting. The server is Apache with mod_fcgid. Database is MySQL.
Would someone give me a piece of advice what to do in such situation?
Thank you!
