-------------------------------------
Hi Dear Chris,

I'm testing eAccelerator 0.9.5.2 on my local machine (Windows 2000 Professional + IIS 5) in order to use it into my server (Windows 2000 Server) then.

In IIS (Home directory, Application Mappings tab) I have .php -> c:\php\php-cgi.exe

I copied eaccelerator0952_5.2.5.dll into c:\php\ext directory and I renamed it to eaccelerator.dll.

Then I modified/added the following to c:\php\php.ini:
cgi.force_redirect = 0
fastcgi.impersonate = 1
extension_dir = "c:\php\ext"

extension="eaccelerator.dll"
eaccelerator.shm_size="64"
eaccelerator.cache_dir="c:\php\eaccelerator"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="0"
eaccelerator.shm_prune_period="0"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
eaccelerator.keys = "shm"
eaccelerator.sessions = "shm"
eaccelerator.content = "shm"
eaccelerator.allowed_admin_path = "c:\Inetpub\wwwroot\control.php"

extension=php_gd2.dll
extension=php_mbstring.dll
extension=php_mysql.dll

* Running a test.php file containing I read:

* If I open the control.php file from the web browser I get the following:

If I try to open other PHP file the "Cached scripts" section always shows the "C:\Inetpub\wwwroot\control.php" only. So, other PHP script seem not correctly cached ("Cached scripts" always shows "1").

How could I solve this strange issue?
Many thanks in advance and... merry Christmas!
