i am at this moment stuck with a problem :
Let's say there is two computers : A, and B.
We do "post request" and "insert in mysql database" with computer A.
I want to refresh a page on computer B (or better, a div with Ajax), when my tables in my database are updated.
The easiest but worst solution that i found is to do a select in the database with a counter, every X seconds for exemple and refresh the page of B if the counter is higher than X secondes before.
How can i do that ? I want a good solution, but quickly realisable.
(Computer A and Computer B aren't in the same page)
