I have an existing Apache 2.2 installation on port 8080
In ServerModule:
ExtRoot -> 'ext-x.y.z\'
ServerRoot -> ''
I copied ext-3.3.0 folder to C:\testapp
I added below lines to httpd.conf
<Directory "C:/testapp">
Options Indexes FollowSymLinks ExecCGI
AllowOverride None
Order allow,deny
Allow from all
</Directory>
Alias /test "C:/testapp"
Here is my URL:
http://localhost:8080/test/testapp.dll
App is working fine.
I think your problem is here.
Don't put the Alias inside section. Put it directly below the section as I did in my example above.
