I am a little confused about how CAD is supposed to work I guess.
Let's see if we can help...
First off, I have a directory, call it abc.
That right there is kind of a red-flag. Not that you're doing anything wrong, but Apache has a weird
notion of PATH_INFO when a real directory exists. And Dispatch relies on PATH_INFO for parsing. You
can check what Apache thinks it is by printing the $ENV{PATH_INFO} in your Dispatch.pm.
I think this is all you might need to see from there:
Directory c:/path/to/abc
SetHandler perl-script
PerlHandler ACD::Dispatch
AllowOverride None
Order allow,deny
Allow from all
/Directory
Why are you using a Directory for this? I'm not sure if that affects what Apache does with PATH_INFO
or not, but I usually use a Location. Especially since your not serving things out of that directory
directly (instead you're using ACD::Dispatch to provide a virtual directory).
Ok, so here is what has been happening:
Go to:
localhost/abc/
Get:
Home, welcome
What is PATH_INFO here? I would expect it to be ''
Go to:
localhost/abc/fdjksalfdsafdsa
Get:
Home, welcome
What is PATH_INFO here? It looks like it should be 'fdjksalfdsafdsa', but Dispatch looks like it's
behaving with a PATH_INFO of ''.
Go to:
localhost/abc/jkfldjskljfdkls/home_othercontroller
Get:
Error'd
Again, PATH_INFO looks like it should be 'jkfldjskljfdkls/home_othercontroller' but Dispatch behaves
like it's home_othercontroller
Go to:
localhost/abc/jkfldjskljfdkls/home_othercontroller/some_rm
Get:
Home/OtherController, some_rm
Similar to the above.
So I guess my questions are: why is it ignoring that first directory?
I think you've hit on a weirdism of Apache changing the PATH_INFO if the real directory (in this
case abc) exists. Try changing the directory name to something else and see if that changes anything.
And
do I actually have to put the startrunmode in the dispatcher? It seems to
be ignoring the one set in OtherController.pm.
No, the start run mode should be executed if no run mode is given in the PATH_INFO. Try turning on
debugging and see if you can get any more information.

Ok, you're definitely right about that. Apache just completely drops
that first bit, which was expected

Because I didn't know how to do it another way? :-) I updated it to this:
Location /abc
SetHandler perl-script
PerlHandler ACD::Dispatch
AllowOverride None
Order allow,deny
Allow from all
/Location
Note: The following has been there all along:
ScriptAlias /abc /path/to/abc
Go to:
localhost/abc/
Get:
Home, welcome
What is PATH_INFO here? I would expect it to be ''
You are correct.
Go to:
localhost/abc/fdjksalfdsafdsa
Get:

Ok, abc has actually always been an alias for a longer name and never
really did exist. Or is an alias the same?

No, the start run mode should be executed if no run mode is given in the

information.
I figured this one out. The problem was that I had the rule
':app/:rm' = {} and it should have been ':app/:rm?' = {}.
Thanks for all of your help, I really appreciate it.
