Hello Treephat,

You can't directly create a junction as you describe.  There are three types of junction:

1) Standard Junction.  Matches on path.  Path is modified to remove junction component:
https://www.webseal.com/app/webapp/page.html  ----> https://host.backend.com/webapp/page.html

2) Transparent Path Junction.  Matches on path.  Path is not modified:
https://www.webseal.com/webapp/page.html ----> https://host.backend.com/webapp/page.html

3) Virtual Host Junction.  Matches on the Host header.  Path is not modified.
https://host.backend.com/webapp/page.html ----> https://host.backend.com/webapp/page.html

In your case, you could use a Standard Junction if you don't mind the reference to webapp being in the URL accessed by customer:
https://www.webseal.com/web1/webapp/page.html ----> https://192.168.10.10/webapp/page.html

If you wanted to replace /web1 with /webapp in the Reverse Proxy you could use an HTTP Transformation to do this.  Transformations are done before junction processing:

https://www.ws.com/web1/page.html -> https://www.ws.com/webapp/page.html -> https://192.168.10.10/webapp/page.html
-                      ----Transformation--->                    -----Junction------>

Modifying the path in this way, you would very likely have issues with Links returned from the backend application which would reference /webapp.  These would arrive back at the client.   They might work in some cases but things like path based cookies could have an issue.  You would need to test.

Cheers... Jon.
