This is not a bug! IE stores downloads in the Temporary Internet Files folder until the download is complete. THESE HEADERS WILL PREVENT DOWNLOAD ON IE!!! Only use the Expires header, after all, it will require the file to be downloaded again the next time. I have the Cache-Control and Pragma headers sent only if not IE. Anyway, I set the Content-Disposition to attachment because I already know that the box will appear. I use it here to make sure the box opens.

Use this if you don't want your PDF to display in the browser (in IE). Then, if it is IE, the "application/force-download" Content-type is sometimes required to show the download box. The Content-Length header is required by some browsers to activate download box. I start out by checking for IE, then if not IE, I set Content-type (case-sensitive) to JS and set Content-Disposition (every header is case-sensitive from now on) to inline, because most browsers outside of IE like to display JS inline. Take a look at this code, which replicates the normal download of a Javascript: Wrapping the previous example in an output buffer actually changes the behavior of the script! This is because headers aren't sent until the output buffer is flushed.Īfter lots of research and testing, I'd like to share my findings about my problems with Internet Explorer and file downloads. You also won't see any "headers already sent" errors because the browser follows the redirect before it can display the error. This redirects to 1.html since the header is sent as soon as the echo happens. This redirects to 2.html since the second header replaces the first. In the case of redirects, if you forget to terminate your script after sending the header, adding a buffer or sending a character may change which page your users are sent to. If you are replacing headers in your scripts, this means that the placement of echo/print statements and output buffers may actually impact which headers are sent.
It is important to note that headers are actually sent when the first byte is output to the browser. That way foo.png will be properly cached by the client and you'll save bandwith.
When using PHP to output an image, it won't be cached by the client so if you don't want them to download the image each time they reload the page, you will need to emulate part of the HTTP protocol. You can usually useĪnd dirname() to make an absolute URI from a Including the scheme, hostname and absolute path. Most contemporary clients accept relative URIs as argument toīut some older clients require an absolute URI The status may be overriddenīy calling header() with a new status lineĪt any time unless the HTTP headers have already been sent. To the client, regardless of the actual header()Ĭall being the first or not. The HTTP status header line will always be the first sent In your script, or setting the output_bufferingĬonfiguration directive on in your php.ini or With the overhead of all of your output to the browser being buffered You can use output buffering to get around this problem, Headers só serão acessíveis e retornados quando a SAPI que os suporta
