Steffen, great work you do! I am much impressed and deeply grateful that such peoples like you exists - thank you!

I have a problem with mod_disk_cache. I got errors like this:
    [Thu Feb 09 09:57:02 2006] [error] (OS 5)Zugriff verweigert : disk_cache: rename tempfile to hdrsfile failed: c:/www_root/cache_root/aptmpyBle12 -> c:/www_root/cache_root/ns1/JhW/b38/13z/Jvc/E240G8g.header
On the net I found many discussions regarding that error like that one:
http://www.nabble.com/-PATCH-fix-incorrect-304%27s-responses-when-cache-is-unwritable-t205089.html

I have no clue whether this patch is in the current version included or not. So I would like to ask you whether you can dig into that subject?

My httpd.conf:
Code:
<IfModule mod_cache.c>

LoadModule disk_cache_module modules/mod_disk_cache.so
# If you want to use mod_disk_cache instead of mod_mem_cache,
# uncomment the line above and comment out the LoadModule line below.
<IfModule mod_disk_cache.c>

CacheRoot c:/www_root/cache_root
CacheEnable disk /
CacheDirLevels 5
CacheDirLength 3

CacheEnable disk http://www.mydomain.de/

# 3600 == (one hour)
CacheDefaultExpire 3600

</IfModule>
</IfModule>

<Directory "C:/www_root/cache_root">
    AllowOverride None
    Order allow,deny
    Allow from all
</Directory>

I saw on the ASF dev list that there are fixes/changes planned for the next version of mod_cache. Do not know the patch you mention is included in the current 2.2.0.

Do you have the error all the time ?

You have a double entry in your conf:

CacheEnable disk /
CacheEnable disk http://www.mydomain.de/

The last one you can remove if you are not acting as a forward proxy server

I just did a quick test with 2.2.0:

LoadModule cache_module modules/mod_cache.so
LoadModule disk_cache_module modules/mod_disk_cache.so
CacheRoot c:/windows/temp
CacheEnable disk /
CacheDirLevels 5
CacheDirLength 3
CacheDefaultExpire 3600

And I see no errors so far.

Does the server run as service? If yes, maybe the service don't have the rights to access the folder.

Good idea ... but unfortunately it runs as "LocalSystem" service and has the rights to access the folder. Perhaps the problem stays in conjunction with the "www_root" folder. I will try to set up the "cache_root" folder separately.

YES! That was the answer! No more problems since setting up the "cache_root" folder separately.

Thanks to all for your suggestions.

Hi Hydn79,
you need a permission setting for the folder

Code:

<Directory "C:/WINDOWS/Temp">
    AllowOverride None
    Order allow,deny
    Allow from all
</Directory>


....
