Deployment help needed

[Jon]

We have a asp.net app that runs like the following in a single-site
scenario.

Directory structure:
c:\inetpub\wwwr oot\myapp - aspx files, global.asax and web.config
c:\inetpub\wwwr oot\myapp\bin - myapp.dll, strings.dll (localized strings),
library.dll
c:\inetpub\wwwr oot\myapp\UserC ontrols - ascx files
c:\inetpub\wwwr oot\myapp\TextB locks - large localized text blocks in html
format
c:\inetpub\wwwr oot\myapp\Image s - site images

We would like to be able to deploy 5 copies of the web app on one IIS server
and do the following: (essentially, we want to share the aspx, ascx, site's
class dll, and images between all the sites and also have each site get its
own web.config and strings.dll and textblocks). Is this possible to do?
I'm assuming we could use the GAC for the site dll, but I wasn't sure about
sharing the aspx and ascx files, etc...

shared things:
c:\inetpub\wwwr oot\myapp_base - aspx files, global.asax and web.config
c:\inetpub\wwwr oot\myapp_base\ bin - myapp.dll, library.dll
c:\inetpub\wwwr oot\myapp_base\ UserControls - ascx files
c:\inetpub\wwwr oot\myapp_base\ Images - site images

each individual site:
c:\inetpub\wwwr oot\myapp_01 - web.config
c:\inetpub\wwwr oot\myapp_01\bi n - only strings.dll (localized strings)
c:\inetpub\wwwr oot\myapp_01\Te xtBlocks - large localized text blocks in html
format

c:\inetpub\wwwr oot\myapp_02 - web.config
c:\inetpub\wwwr oot\myapp_02\bi n - only strings.dll (localized strings)
c:\inetpub\wwwr oot\myapp_02\Te xtBlocks - large localized text blocks in html
format

Thanks for any help on this!
