206 is partial content... does the status come back instantly or does it take a while?  It could be that your max_execution_time is set lower than the time it is taking to send this pdf.  How big is the pdf anyway?

Since it goes so fast I'm guessing the server never gets to the file so it's not a size problem.

Your server logs should be where the ErrorLog directive (if there is one) points to in your apache configuration file (or virtual host file) - most of the time it'll be under /var/log/apache2 or /var/log/httpd - but it could be anywhere.  For a server problem this is the best place to look - you may have to tweak the error_reporting directive in your php.ini if you see nothing.

Also, make sure the file exists, is a (valid) pdf, and is readable by the user running your server.  It should be under <ezpublish root>/<VarDir>/storage/original/application.  VarDir is the parameter supplied in the site.ini under [FileSettings].  If you have access to the database you can find the hash.pdf that corresponds with the original filename.pdf.

The ezpublish logs are under <ezpublish root>/var/log but if it's a server problem there probably won't be any relevant errors.  But check anyway.

Are your rewrite rules working?

Rewriterule ^/var/storage/.* - [L]
Rewriterule ^/var/[^/]+/storage/.* - [L]

This should keep a request for a file in <VarDir>/storage from going to index.php

To help debug rewrite rule requests (with apache) you can set something like this:

RewriteLog /var/log/apache2/rewrite.log
RewriteLogLevel 1

The RewriteLogLevel can be set anywhere from 1 to 9 but it quickly becomes overwhelming so keep the number low... also it slows the server down and can create large log files so you definitely don't want to forget to turn this off.

Other questions to ask if the above is not the problem:

Is this pdf a valid file?  Does this happen with all pdfs/all storage files?  Did someone remove application/pdf from your mime.types file (assuming you are using apache)?  Is there something custom about your index.php?  Did this use to work with a previous version?

@Douglas - interesting.  But, if it turns out to be this, then it's not working with firefox (3.x or 4.x) either... because that's what I tried to use to download the file above: http://etnaworldtrade.domenicogarozzo.it/Media/Files/Articolo-di-giornale

Hi Steven, (sorry for the inappropriate. I don't want click the button.)

my .htaccess file content is:

DirectoryIndex index.php
RewriteEngine On
RewriteRule ^api/ index_rest.php [L]
RewriteRule ^index_rest\.php - [L]
RewriteRule ^([^/]+/)?content/treemenu.* index_treemenu\.php [L]
RewriteRule ^var/([^/]+/)?storage/images(-versioned)?/.* - [L]
RewriteRule ^var/([^/]+/)?cache/(texttoimage|public)/.* - [L]
RewriteRule ^design/[^/]+/(stylesheets|images|javascript)/.* - [L]
RewriteRule ^share/icons/.* - [L]
RewriteRule ^extension/[^/]+/design/[^/]+/(stylesheets|flash|images|lib|javascripts?)/.* - [L]
RewriteRule ^packages/styles/.+/(stylesheets|images|javascript)/[^/]+/.* - [L]
RewriteRule ^packages/styles/.+/thumbnail/.* - [L]
RewriteRule ^var/storage/packages/.* - [L]

RewriteRule ^favicon\.ico - [L]
RewriteRule ^design/standard/images/favicon\.ico - [L]

RewriteRule ^robots\.txt - [L]

RewriteRule ^w3c/p3p\.xml - [L]
RewriteRule .* index\.php

The file is a valid PDF.
I can open it with Preview.

Does not work.  This looks identical to what I had before I fixed the ezFile class.

Did you apply the patch in the issue I listed?

Add a line to ezFile just before line 253

$tempString = ( $overrideFilename !== false ) ? "; filename={$overrideFilename}" : '';

Then use xdebug to see what $tempString is.

You will find is is something like "; filename="

This is an invalid header.

You need to change line 256 to:

(( $overrideFilename !== false ) ? "; filename={$overrideFilename}" : '')

Note the surrounding ()

Also on line 260 make it:

if ( $startOffset !== 0 )

Or it will always use partial handling as ezfilepassthroughhandler(i thing that was the name) always passes a filesize which will make it use the partial handling.
