Post subject: PDF decompression on client from IIS compressed source
Archived from groups: microsoft>public>inetserver>iis (more info?)
Hi all.

From checking around on the net and from viewing some 3rd party HTTP
compression applications for IIS I have noticed that there appears that
there is a problem with decompressing PDF's on IE browsers. (maybe others
but I haven't checked)

Has anyone who has implemented compression on IIS (5 or 6) had issues with
PDF's being decompressed incorrectly on the client or do you exclude PDF's
from being compressed in the first place?

Our testing has shown random errors at times. Some times a refresh of the
page retrieves the document correctly afterward.

We want to implement compression to remote sites running on low bandwidth
but we need PDF compression to occur as that is where most of our gains will
be made.

Thanks in advance for any help/advice you can give.

All the best,
Tony

My experience is that it's not just PDF files which have trouble with
compression; HTML and CSS can cause trouble as well. The problem appears to
be linked to non-updated versions of Internet Explorer, so if you can
control this factor then maybe you won't experience these problems.

Hi Ian.

Firstly, thanks for your reply.

I guess I just need to clarify what you mean by non-updated IE. We've
updated to IE 6 sp1 plus hot fixes (in most places anyway Smile. Above what
version do you think that the problem went away?

Some of the test machines using this version (outlined above) have
experienced the problem intermitantly.

It surprises me that Microsoft haven't fixed this issue as it seems to have
been around for a long time.

All the best,
Tony

I'm not 100% sure as personally I've never experienced the problem, but I
think it was probably fixed in sp1 of IE 6. I've generally just advised
people to use Windows Update and get the latest updates which has generally
solved the problem.

Hi again Ian.

Personally I don't think it has been solved as we have experienced this
issue in IE 6 SP1 + Hotfixes.

Thanks anyway Ian.

All the best,
Tony
