reload cache, reload other page web… using javascript

[petterrjx]

I would like to do this:[*]A web page A showing a video.ogv (using cache) in Chrome. The video.ogv is a file in a local folder[*]Then, I close and reopen Chrome, displaying a web page B with a button. In this step, I change also the content of video.ogv (but not its name) in my folder.[*]I push the button in B to open the page A using \[code\]window.open("http://pagewebA,"_parent");\[/code\]Result: Chrome uses the first content of video.ogv. I would like to display the video.ogv with the new content.Some solutions: a) I could disable the memory cache, but in this case I can have problems to display the video after window.open. The video on the page A is black b) I could keep the memory cache and force to reload the cache using \[code\]window.open("http://pagewebA?x=1","_parent")\[/code\]; but In this case also my video is black.I mean, a) and b) give me a black video. I think the page A can't download the video properly because of its size, and consequently the display is black. If I keep the cache memory and refresh the web page after using window.open, I can display the video.Some questions for possible solutions: [*]Is it possible to use JavaScript in the page B to reload all cache before using window.open? Or maybe it's better to reload the cache related to a page (in my casem page A) before using window.open? Or maybe reload other web page in the background... But how?[*]Is it possible to preload a video or any file in the page B that I would use in the page A? How? [*]Any other possible solution?I am using the HTML5 \[code\]<video>\[/code\] tag to display the video in the page A.
