I'm currently trying to put together a proof of concept
on mixing various technologies onto one web site in order to ease migrations and
add flexibility.
The idea is to create one 'mashup' site behind an IIS 7.5 ARR reverse proxy.
For the time being the ARR reverse proxy forwards all request to our main site.
The request are as follow:
client -> ARR: Get /
ARR -> Server 1: Get /
Server 1 -> ARR: 200: /index.htm
ARR -> client: 200: /index.htm
...so far so good.
Let's say, I want to
add a new site (root of another server) as a subsite of my main website.
a simple inbound rule does the trick:
<rule name="sub1" stopProcessing="true">
<match url="^mySubsite(.*)" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false" />
<action type="Rewrite" url="http://server2/{R:1}" />
</rule>
The requests now are:
client -> ARR: Get /mySubsite
ARR -> Server 2: Get /
Server 2 -> ARR: 200: /index.htm
ARR -> client: 200: /index.htm
... still ok.
The issue comes when the site
on server2 sends a redirection (e.g. to a login page). In the case of SharePoint, it will redirect the user to: /_layouts/Authenticate.aspx?Source=%2F
...which does not exists:
client -> ARR: Get /mySubsite
ARR -> Server 2: Get /
Server 2 -> ARR: 301: /_layouts/Authenticate.aspx?Source=%2F
ARR -> client: 301: /_layouts/Authenticate.aspx?Source=%2F
client -> ARR: Get /_layouts/Authenticate.aspx?Source=%2F
ARR -> client: 404: Not Found
Does anyone know a way write the outbound rule to rewrite the response from server 2 "301: /_layouts/Authenticate.aspx?Source=%2F" to "301: /mySubsite/_layouts/Authenticate.aspx?Source=%2FmySubsite%2F"?
