It is possible to route cf requests for subfolders in one Website to different installed Cold Fusion servers

Hello,

For a migration scenario we think about to migrate application step-by-step from CF9 to CF11. So on the server, we want to replace the modified code with changes for CF11 and connect this whole application, which is a subfolder of a website, to CF11 instead of the current running CF9.

So in IIS we have

One Default Web Site with different applications like

--- app1

--- app2

---app3

All these apps are currently connected to the CF9 version with WSConfig tool.

Now, the app1 was modified to match CF11 requirements, and we want to connect the folder app1 to CF11

in the browser it was http://servername/app1  and http://servername/app2

The tool used by CF to setup the websites in IIS will only do it at top level. So the Default Web Site, it wont apply to folders below it. This is because it makes changes to the ISAPI filters which can only be changed on the website level not subfolders.

You would have to setup different websites for each app for this to work.

Yes, but it was also possible to change the File Handler per subfolder, so I can imagine, that I change the extension handler settings for .cfc and .cfm from D:\ColdFusion9\config\wsconfig\1\isapi_redirect.dll changing to D:\ColdFusion11\config\wsconfig\1\isapi_redirect.dll

You could try it, but the top level ISAPI filter will still be using CF9's dll, which means there will be a conflict, and most likely causes errors.
