Re: [PHP] Finally, PDF Header for PDF stuffs that work....
IE just don't work depending on some of the IE's version because of the IE's countless bugs. So, a different method of controlling the data output to the browser is needed. That's when I use the fopen() stuffs and it solve the problem. It is evident by reduced customer's calling tech support (us)... Questions about IE problem is something you would have to ask M$ on why it is using hte faulty IE. Scott F.

Re: [PHP] Finally, PDF Header for PDF stuffs that work....
OK, here's a different problem. If I call a pdf file directly, the Acrobat plugin begins to display the file almost immediately. Here is the reponse header for calling the file directly: HTTP/1.1 200 OK Date: Thu, 16 Oct 2003 20:41:28 GMT Server: Apache/1.3.27 (Unix) (Red-Hat/Linux) mod_ssl/2.8.12 OpenSSL/0.9.6b PHP/4.3.3 mod_perl/1.26 X-Meta-MSSmartTagsPreventParsing: TRUE X-MSSmartTagsPreventParsing: TRUE Last-Modified: Thu, 16 Oct 2003 17:08:17 GMT ETag: 94174-341fcb-3f8ed081 Accept-Ranges: bytes Content-Length: 3416011 Connection: close Content-Type: application/pdf I wrote a pdf-serving script for anti-leech purposes, and it works fine, except that the acrobat plugin waits for the entire file to come down the pipe before anything is displayed. The mystery for me is that the headers--the important ones anyway--look exactly the same.

I don't think the average user will have the patience to stare at a blank browser waiting for the file.

I don't think the average user will have the patience to stare at a blank browser waiting for the file. This is a pdf issue I believe. There is an option in the PDF called 'Fast Web View', if this is set adobe doesn't need to read the whole thing before starting to view. Check the pdf's 'Document properties' and You'll see if the option is set or not. If not, resave the document enabling that option. Acrobat 5 has a nice little batch thing to convert serveral docuements into this mode.

But I still don't understand why calling the file directly gives immediate output, but if I generate the headers and readfile() the file to the browser (same exact file) it waits to get the whole file. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Are you saying readfile() somehow avoids loading the whole file into memory? maybe it does, you learn everyday, I am just wondering...

Imagine if readfile did read the whole thing into memory. and you have a script was sending 100MB files to the users and then 10 people happend to come across your site at the same time. your system will require, at minimum, 1000MB's of memory to send the files. And cross your fingers the site doesn't get posted to a BBs.
