Problem with rabbitweb server

I have problem with the rabbitweb server (card : BL4S160).
I have some html and js files. When I try to access to a 90-100KB js or html file, the http request is very long and is finally reseted by rabbit.
Is there something to do ? Or those files are to big for rabbit ?

Are you having any issues with the Standard Dynamic C Rabbitweb samples?

I’ve tried with zimport.c.
With this sample it works but if I modify the alice.html to make it bigger, it fails sometimes (connection is reseted by rabbitweb).
