We're using the ARR extension to IIS to rewrite requests to a website running a different app pool using the server farm feature.
I want to be able to set a custom header on the response when I generate my page inside the server farm, but it's getting stripped out as it comes through ARR.
I tried using the <serverVariables> functionality, but that only lets you add headers from the ARR routing website into the request as it goes into the website with the pages, not the other way around.

I have a website on the IIS as the default website. It is in "c:\interpub\wwwroot". When I request "www.mysite1.com", I get to this site.
Now I want to add a second website on the same IIS server. I want to store it in "c:\mysecondsite". When I request "www.mysite2.com", I wish to get to this second site.
NOTE: I don't want the second site to become an application inside the first site. In other words, I don't want to access the second site using "www.mysite1.com/mysite2".
How do I do it?
How can I display custom HTML instead of the following 502 response from ARR?
Traffic is directed to the server farm using a URL Rewrite rule on the server level.
Open IIS and then on the server level, in the IIS section, click "Error codes". These files are global, which is the level you will want to change for your situation. There are also site level error pages. You can modify these files or you can point them to a different file that you have customizedIIS Error Pages.
I essentially have the same issue as desribed here Redirect HTTP to HTTPS in Azure Application Gateway but am trying to solve it a different way.
My back end web application works fine when both http and https are open on the AAG, however when you click on a link generated by the webapp to another page the url sent back to the client is for http not https. Obcviously the proper solution is to make the web app aware it is behind a reverse proxy and generate links accordingly.
In the short term I have been attempting, and failing, to use the IIS url rewrite module to either:
a) Using an inbound rule, rewrite (not redirect) the incoming URLs as https which ought to force the responses to contain https urls (a redirect causes an infitite loop as AAG forwards everything to the back end web servers as http). I'm guessing this is impossible because its essentially creating a secure channel between itself.
b) Using an outbound rule, rewrite the responses so the urls are https instead of http. This is proving to be very difficult as I don't understand what parts of the responses I need to be modifying. I'm hoping this approach is possible though?
For the uninitiated, the answer is to use custom tags in an outbound rule, which match the html elements containing the values that need modifying.
The drawback is of course that it means the web server is having to do a patter match & replace on every single page it serves unless you can use conditions to limit the scope. Still very inefficient compared to fixing the code so it is proxy aware!
We have an IIS web farm, of which consisting an load balancer, 4 ARRs, and 2 ASP.NET application servers running DNN CMS. The 4 ARRs will URL rewrite to DNN application servers. We have more than 100 URLs that need to be redirected into more specific resources within the website.
For example, when a user types in http://www.abcd.com/product1 from outside, the desired outcome is to redirect to www.abcd.com/index.aspx?articleid=1234 , we have configured such behavior within DNN environment, and we can sure that it works, as when we browse the site within the DNN application server, the DNN is able to detect the URL and perform redirection accordingly.
Problem occurs when we attempt to browse the http://www.abcd.com/product1 from LB and ARRs, when we type http://www.abcd.com/product1, it simply go back to http://www.abcd.com mainpage, which the redirection doesn't work at all. No IIS level HTTP redirection has been performed at the ARRs and LBs, the only setting is the default URL rewrite rule which will rewrite the URL to backend DNN servers.
Same question has been posted in IIS forum as well, it is just that I decided to post it here again to gain more exposure.
When going through the ARR are you calling off to the specific IP? For example does http://www.abcd.com/product1 become http://xxx.xxx.xxx.xxx/product1 by chance?
If so, you might want to add those as additional portal aliases to the DNN site.
Otherwise, you will might want to use something like Fiddler to see exactly what is going on with redirects/responses.
What I'm trying to achieve:
Intercept requests for .asp files using an asp.net application
then re-write the url to something search engine friendly
then pass the request onto the asp.dll to handle the request.
How Im trying to acheive it:
I'm trying to get intelligencia url re-writing working for a classic asp application by
changing the IIS mapping for the website so that .asp extensions are handled by an asp.net application.
The intelligencia asp.net url re-writer then rewrites the url.
The requested .asp page is then forwarded to the asp.dll for processing. Can this bit be done? Any ideas?
My limitations:
Shared hosting account so I can't install isapi filters on the server.
Does it sound like something that could be done by writing an HTTPModule?
I've considered 301 redirect instead but am concerned about google ranking problems.
A .NET HttpModule cannot forward requests to Classic ASP in II6 because of the way the pipeline works. By the time your .NET module executes, you are in the ASP.NET handler and cannot transfer to the ASP handler.
IIS7 has the Integrated Pipeline, which would allow you to have a .NET HttpModule re-write the request to the Classic ASP handler.
You could have a custom 404 handler that clears the 404 status from the response and does a Server.Transfer or Server.Execute your page. The only thing is that you can't pass querystring parameters, so you page would need to parse the request and pull out the variables by hand.
I use a modified version of Smart404 to handle SEO friendly urls, moved files, etc. They call the feature "virtual_aliases".
