serving PDF documents
|

| Patrick Dicaire 2004-04-28, 4:33 pm |
| Hi,
Wondering if anyone ran into this issue before...
Just migrated from IHS on iSeries to an xSeries (windows 2000). Using IHS
2.047.
Every time a user tries to open a PDF document off our web site, they get an
error in their acrobat reader saying "The file is damaged and could not be
repaired"
Been looking for a while on the net but all messages are mentionning to
uncheck the "preview PDF in browser" settings in the acrobat preferences.
Obviously we can't tell all our customers to do this!
If we open the PDF from the windows shared it opens correctly, but not when
served from the web.
Any help is appreciated...
Thanks in advance,
Patrick Dicaire

| Hi,
Covering the basics is great because I'm not an expert in HTTP servers.
Not sure what you mean with correct MIME type. I've added the following line
to the http.conf file
AddType application/x-pdf *.pdf
In regards to the mime modules I have the mime_module loaded but not the
mime_magic_module
LoadModule mime_module modules/mod_mime.so
#LoadModule mime_magic_module modules/mod_mime_magic.so
Not sure if that's enough info.
Thanks,
Patrick

| Yes, we ran into this a while ago. 
Our problem was when we tried to serve PDFs from our iSeries server. I
believe the PDFs were generated on-the-fly by an outside company on some
other platform. But when we placed the final PDFs on our server we would
get sporadic errors. I was able to eliminate Acrobat Reader as the
problem because I could right-click on the link and save it to the
desktop and the resulting file would not be the same size as the
original. And the file would get truncated at different places (be a
different size), too.
I think it had something to do with the operating system (or perhaps the
browser). We might have even had IBM tech support analyze the server
communication trace logs and, if so, they said the problem was the
client was having trouble reassembling the TCP/IP packets and would
issue a reset. (I'm not sure I'm remembering correctly, here).
Why this happened with these PDFs I don't know as we have other PDFs on
our server and I'm not aware of any problems. Perhaps the size had
something to do as I think the ones that failed were in the 3-6M range
and the ones we create are in the 100-400K range.
We never did get this resolved and had to go back to another solution.
Perhaps you can try different platforms and browsers and see if you can
figure it out. Our fear was that it was something in the client OS
(Windows, with older versions showing the problem more often than newer
ones) but maybe you can find something else.

| This is what I have in my mime.types file :
application/pdf pdf
This file (mime.types) is included in the httpd.conf by the following
directive:
TypesConfig conf/mime.types
On other note:
There are known problems with serving pdf on the web when you are using very
long URL or large pdf (more than 4MB) or with very large file headers.

| Our problem seems to be resolved. We can't pinpoint what the problem was.
We changed a few parameters in the http.conf file but did not notice the
changed immediately until we cleared the Temporary files on the clients.
Thanks for all your help!

Stevers,
what other solution did you end up turning to?
