Errno::EINVAL happens in Windows environment when enabling caching and reloading

[tune]

I've found that Errno::EINVAL happens when reloading and caching are enabled.

Reproduce is easy, create blank project and add following setting in "app/app.rb".

set :reload, true
register Padrino::Cache
enable :caching

When reload event happen, following log messages are displayed.

ERROR -  Errno::EINVAL: Invalid argument - C:/Users/tune/Desktop/sample/tmp/Sample::App; C:/Ruby200/lib/ruby/2.0.0/fileutils.rb:245:in `mkdir'

It seems that cache library try to create folder, but folder path includes ":" character that is not allowed in windows environment.

@tune Thank you!

@padrino/core-members Is this directory name correct? (Sample::App)
I guess the cache directory name should same as the production environment.

I can confirm, there is an issue with reloading and Padrino::Cache: tmp/SampleApp is generated on reload, while tmp/sample/app is generated on clean app load.

[namusyaka]

Yeah, this behavior may be caused by this line.

I fixed it and trying to add a test now.

@ujifgc Great, thank you!

BTW, I was struggling with 2 folders being created in my temp folder: application and Application. Now it's resolved.
