Content-Type: application/pdf Content-Disposition: inline; filename="tvnovellas.info . header("Content-Type: application/force-download"); header("Content-type. Solved: When adding a PDF as attachment to a page, the content type of the attachment is usually set to application/pdf. However, sometimes it is. It#;s quite a common scenario with the web to want to force a file to some http response headers: Content-Type: application/octet-stream.

Yet, at least half of them share common errors; in many cases programmers simply copy the code from something that works, without even attempting to understand what it really does. What follows is not a complete working download script, but rather a set of issues you should be aware about and that will allow you to write better code. Guessing is not too difficult and in a few tries, an attacker could obtain configuration or password files. What you must do — always — is sanitize the input. Anything is better than blindly accept requests. If you need to restrict access to a file, you should generate encrypted, one-time IDs, so you can be sure a generated path can be used only once. Use headers correctly This is a very widespread problem and unfortunately even the PHP manual is plagued with errors.

Only use the Expires header, after all, it will require the file to be downloaded again the next time. This is not a bug! IE stores downloads in the Temporary Internet Files folder until the download is complete.

I know this because once I downloaded a huge file to My Documents, but the Download Dialog box put it in the Temp folder and moved it at the end.

Server content-type setting for PDF

Just think about it. If IE requires the file to be downloaded to the Temp folder, setting the Cache-Control and Pragma headers will cause an error!

I hope this saves someone some time! My files are in a compressed state bz2. When the user clicks the link, I want them to get the uncompressed version of the file. After decompressing the file, I ran into the problem, that the download dialog would always pop up, even when I told the dialog to 'Always perform this operation with this file type'.

As I found out, the problem was in the header directive 'Content-Disposition', namely the 'attachment' directive. If you want your browser to simulate a plain link to a file, either change 'attachment' to 'inline' or omit it alltogether and you'll be fine. This took me a while to figure out and I hope it will help someone else out there, who runs into the same problem.

The new URI is not a substitute reference for the originally requested resource and is not cached. Otherwise you will face problem of headers not being properly sent eg. Cannot modify header information - headers already sent by output started at C: Just to inform you all, do not get confused between Content-Transfer-Encoding and Content-Encoding Content-Transfer-Encoding specifies the encoding used to transfer the data within the HTTP protocol, like raw binary or base Eg Use: If you want to remove a header and keep it from being sent as part of the header response, just provide nothing as the header value after the header name.

For example PHP, by default, always returns the following header: Fri, 16 Oct I just want to add, becuase I see here lots of wrong formated headers. All used headers have first letters uppercase, so you MUST follow this.

For example: Then there MUST be colon and space, like good: Location header MUST be absolute uri with scheme, domain, port, path, etc.

This is helpful if you want a javascript or similar client-side function to execute a server-side function without refreshing or changing the current webpage. Great for updating database, setting global variables, etc. In the bottom note: But the strange behaviour of dirname is a problem for URL ending by a directory without file name!

It's not the same without you

We encountered a situation where the script accessed by the redirection wasn't loading the session correctly because the precedent script hadn't the time to update it we used a database handler. The header call can be misleading to novice php users. Here is a php script I wrote to stream a file and crypt it with a xor operation on the bytes and with a key: The user is now asked for a md5 password instead of keeping it in the code directly.

If you still get strange results when downloading especially in IE , make sure that the PHP output compression is disabled, as well as any server compression sometimes the server inadvertently applies compression on the output produced by the PHP script. Handling large file sizes readfile is a simple way to ouput files files.

If you have output buffering, the file will not be sent to the user in chunks but only at the end of the script. At the start of your script, after checking the file if it exists, etc.
