Hi,I found some articles on the web. This problem has occurs since 2002 !! Yes !
But unfortunately, I could not find any article with a real solution ! For instance : - Disable mod_deflate (obsolete anyway with 2.0.x) - Upgrade to 2.0.40 (I have a 2.0.50) - Comment in the magic file the line dealing with pdf - Replace in the mime file application/pdf in application/x-pdf- Some people said it happened with large pdf file (over 100kb) : for me, even a 78kb can't work !
- and certainly many other tips.... I did more tests :Using wget (under Windows), I download the same file. I even save the file with the "Save Targer as" option.... I read the PDF file with an hex editor.... I promise you, it does not look like the original !!!! It's even ugly !!
After several attempts, I found THE solution !! First, in the etc/magic (and maybe magic.default), comment the line : 0 string %PDF- application/pdf Then, add this line in the httpd.conf file : AddType application/x-pdf pdfNote that, instead of the last modification, I tried to edit the mime.types files. But, no effect. Only the "AddType" directive works!
Now, I will sleep better tonite... but I'd be interested if somebody could explain me the reason !!

Hi, I use Apache2 on Mandrake 10.1. I installed it recently. I build a simple web site which allows to download tips as PDF Files. I created the original PDF Files on my computer. I can read them with no problem. I transfered them to my website, first using Samba. I notice then that some files could not be correctly read : IE tells me (or rather Adobe Acrobat plugin) that "The file does not start with '%PDF-'" ! I did the test on severeal computers... Ok, I thought the files were corrupted. I transferted them again but with ftp... same problem ! I decided to transfert somewhere else the files on the same server, then I compared (using diff) each "bad" file with the new copy : no difference !!! For heaven sake, what's wrong !! Argh !!! Thanks for your support !
I don't think anything wrong with the PDF files themselves. The problem is they got compressed when they are transfered from the web server to the browser. Some browsers don't like it and hence the "The file does not start with '%PDF-'" error. Google can tell more about that error. We've ever had that problem. If the mod_deflate.so module is loaded in your httpd configuration file, you can turn of compression for PDF files. The following config works for us. === # Turn on compression <Location /> # Insert filter SetOutputFilter DEFLATE # Netscape 4.x has some problems... BrowserMatch ^Mozilla/4 gzip-only-text/html # Netscape 4.06-4.08 have some more problems BrowserMatch ^Mozilla/4\.0[678] no-gzip # MSIE masquerades as Netscape, but it is fine # BrowserMatch \bMSIE !no-gzip !gzip-only-text/html # NOTE: Due to a bug in mod_setenvif up to Apache 2.0.48 # the above regex won't work. You can use the following # workaround to get the desired effect: BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html # Don't compress images SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip dont-vary # Or pdf SetEnvIfNoCase Request_URI \.pdf$ no-gzip dont-vary # Make sure proxies don't deliver the wrong content Header append Vary User-Agent env=!dont-vary </Location> === Bing --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
