http-headers

I want to download an image from the 'net and set it as the users background. This works great over wi-fi, and some 3G networks, but others (T-Mobile UK, for sure) seem to compress the images before sending them. This effect is noticeable when using the browser, too - however, if you long press on an image and save it, when viewing in the gallery it is either not compressed at all, or substantially less so. I want to be able to do this in my own app. I assume it has something to do with the HTTP headers, but of the ones I've modified, none has made a difference. Can anyone help me out here?

A site I am working on that is built using PHP is sometimes showing a completely blank page. There are no error messages on the client or on the server. The same page may display sometimes but not others. All pages are working fine in IE7, Firefox 3, Safari and Opera. All pages are XHTML with this meta element: <meta http-equiv="Content-Type" content="application/xhtml+xml; charset=utf-8" /> It appears that I have fixed the problem by adding this PHP code: header('Content-type: text/html; charset=utf-8'); I have read that this problem may be caused by XHTML, encoding, gzip compression, or

I'm making a website using the Symfony framework, on an ovh server. When an user changes page, I create a new XMLHttpRequest to avoid to reload all the page and improve user experience. Everything works well, but I want to add a loading bar while the next page is loading asynchronously. Unfortunately the lengthComputable parameter was false. To go through this issue, I've set the header on Symfony3 just before sending the response with theses lines : $length = strlen($event->getResponse()->getContent()); $event->getResponse()->headers->set('Content-Length', $length); $event->getResponse()-
