Why browser is looping

Hi

I have used post method of form and when i click on submit data, form posts the data and also if data is not valid then server side code gets executed and prints the error message. however its looping , i thought it would be because of i don't redirect the page to destroy form data, and then i redirected the page using php header..its still looping sometimes

Does anybody know what could the possible reasons for happenning such thing ?

 

Post your code, please.

 

Nico, Actually i cheked my php code in localhost, its not looping... and also i have checked the same file on two different server, its working fine in one server and its looping in other one..so im thinking it must b server issue .. but don't know what can cause this problem on server! do you have any idea ?

 

Whether it's a server problem or not, it's being caused by the code. So it'd be VERY helpful if you could post it.

 

In a loop do you mean the screen keeps refreshing or is the browser keep loading?
