Header download file

Be aware that multiple ranges can be specified e. If the range is not valid, you must output. Do not try to guess or fix the range s as it may result in corrupted downloads, which are more dangerous than failed ones.

Many developers forget to send the code or the Accept-Ranges. Yet others forget that when you send a range, the Content-Length must match the length of the range rather than the size of the whole file. You can output the file using the method described above, skipping until the start of the range and delivering the length of the range.

I did my best to provide only accurate information. It would be truly sad for me if an article about avoiding common PHP errors contained errors itself.

Regardless, my point stands: PHP makes it easy to hack together code that appears to be working, but developers should read and adhere to the official specifications. Great post. Im having issues though. Im trying to get the remote files with using headers but it kills the ability for the user to be able to stream the podcast. BTW I found this post that was exactly what i needed and works great! It sends a bogus error if the range is not accepted and sends the full file size as the content length rather than just the length of the range.

Now, browsers are probably coded to cope with all sorts of errors, but we should strive to write correct code, not just working code. This method works for now and I plane to develop a better functioning version of this. Share on facebook. Share on twitter. Many distributions including Debian,Fedora, and others regularly includerecent versions of cairo. As more and more applications depend oncairo, you might find that the library is already installed.

To getthe header files installed as well may require asking for a -dev or-devel package as follows:. You probably want at least the zlib, cairo, and libpng run-time archives you can search on those strings to find them in thepage. That should be it. Just pop libcairo In general, fink is more conservative about upgrading packages thanMacPorts, so the MacPorts version will be closer to the bleeding edge,while the fink version may well be more stable.

If you want to stay on the absolute cutting-edge of what's happeningwith cairo, and you don't mind playing with software that is unstableand full of rough edges, then we have several things you might enjoy:.

We may from time to time create a snapshot of thecurrent state of cairo. These snapshots do not guarantee API stabilityas the code is still in an experimental state. Again, you'll want bothcairo and pixman packages from that directory. The cairo library itself is maintained with thegit version control system.

You may browse thesource online using the cgitinterface. You may also use git to clone a local copy of the cairo library sourcecode. The following git commands are provided for your cut-and-pasteconvenience. Once you have a clone this way, you can browse it locally withgraphical tools such as gitk or gitview. You may also commit changeslocally with 'git commit -a'. These local commits will beautomatically merged with upstream changes when you next 'git pull',and you can also generate patches from them for submitting to thecairo mailing list with 'git format-patch origin'.

To compile theclone, you need to run. You may need some distribution-specific development packages to compilecairo. If your are using Debian or Ubuntu, you may findadditional details for Debian-derived systemshelpful.

You can use Git on Windows either with msysgit or git inside Cygwin. Msysgit is the recommended way to go as the installation is much simpler and it provides a GUI.

See the msysgit project for thelatest information about git for Windows. You'll find a. This is all you need to do. Download and run the Cygwin Setup. Is followed by a string containing the original name of the file transmitted. The filename is always optional and must not be used blindly by the application: path information should be stripped, and conversion to the server file system rules should be done.

This parameter provides mostly indicative information. When used in combination with Content-Disposition: attachment , it is used as the default filename for an eventual "Save As" dialog presented to the user.

Warning: The string following filename should always be put into quotes; but, for compatibility reasons, many browsers try to parse unquoted names that contain spaces.

This simple HTML file will be saved as a regular download rather than displayed in the browser.
