I am developing a mobile website and i have noticed a strange behaviour while testing with some Nokia smartphones such as C6, N97 or N8. It seems that some http requests are randomly not sent by the browser. The result is that, sometimes, css files or pictures are missing on the page.
This behavior is not systematic and can happen on any page. From my testing it seems that the problem occurs more often on the pages that do a lot of consecutive http requests.
I have tried to reproduce this problem with other websites. Apparently i have the same kind of issue with amazon.com mobile website. Sometimes pictures are not displayed on https pages only. As my website uses only https, i am guessing it could be linked with https.
Is this a known issue? Is there a way to investigate this kind of problem? Any help is welcome!
