I implemented a customer side interface making something call towards the server using JS within an http GET. When checking my access logs, I observe that sometimes, I recieve multiple demands sometimes as much as 6 inside a second-- Making the identical request-- in the same ip -- exactly what do u think this informs ?

Thanks

It could tell they are behind a proxy. (the IP the thing is is really the proxy's IP)

It may be 6 different computer systems behind one router, all going to your page. Or 6 an eye on one browser of 1 computer. Or perhaps a bug inside your JavaScript?
