This question has surfaced on the forums before, but never completely resolved.

The problem.
Enable Druapl Cache (For performance) and enable PHP Zlib compression i.e. set
'zlib.output_compression = On' in php.ini (for Bandwidth).

This leads to problems with viewing the page in IE. The user gets internal Error 500 with
something like
[17-May-2006 12:02:54] PHP Warning: gzinflate(): data error in /bootstrap.inc on line 529

I tried fixing the set_page_cache as per this patch.
But no luck.

Any one, facing this same problem ? The only solution seems to be to disable either Drupal Cache or PHP Compression.
but they both serve 2 diff purpose, and so are both necessary.

The thing to note is, that so far I have seen the problem only in IE not with Firefox , konqueror etc. But making the site work
with IE is also important.

thanks

I am running Drupal 4.7 on Apache 1.3.33. Database is Mysql 4.0.25. This is a shared host so I can't change Apache or MySQL.

In case this info is helpful - I am not having any problem with this. I have:

Drupal 4.7
PHP 4.4.2
MySQL 4.1.18
Apache 1.3.34
Red Hat Enterprise Linux 3

zlib.output_compression - On
Drupal Page Cache - enabled

No problem with Drupal in either IE6 or Firefox

What version of Zlib are you running?

thanks for the reply,

zlib is 1.1.4 , I don't have a root on the box, but I see a /usr/lib/libz.so.1.1.4, so I assume it's 1.1.4.

For now, I have removed compression code from cache. i.e. the pages are cached, but not stored compressed.
But in the long run this is bad for database size.

I also read that this could be because of some UTF issues with MySQL , but don't know how to work on it.

btw, what's the easiest way to determine the size of data stored in a blob ?

thanks

It shows the size of Blobs in its records (in 'data' field in the 'cache' table for example).

Of course I only see IE when I check to see what css bugs to tackle. But I'm getting no negative feedback from the client while site is in pre-release development.
