I have many sites hosted on IIS on same machine. Only for one site, I need to have reverse proxy setup. I have written rewrite rules for this site and forward some request to another site hosted on different machine.
Will enabling proxy on application request routing affect other sites? Will it have an affect the performance of other sites?
Eg: I have following websites(few are wcf services)
localhost/A
localhost/B
localhost/C
localhost/D
Only the website C needs reverse proxy, so I have written rewrite rules for it. How will enabling proxy effect A, B and D sites
Yes you can enable Reverse proxy for one website and ensure that it does not affect the others.
You mentioned that you have 4 websites but in the example, you gave description of "application" and not website. Since its unclear what your architecture looks like, I'll go ahead and give solution to both.
Considering you have a single website and multiple applications within it but you want to enable proxy for just one application, following is what you need to do. Open the URL rewrite section, under pattern, choose regular expression and add ^application_name/(.*) For example, ^c/(.)
But if you have multiple websites and want to reverse proxy just one of them, then open URL Rewrite and add a condition for "HTTP_HOST" and its value. This will ensure that only requests for specific website's hostname will be reverse proxied.
With respect to performance, having URL rewrite on one of the websites will not have any impact on other websites. If you are still unsure and want to play it safe, you can have each website running on separate application pool. That way they have their own w3wp process and are independent of each other.

I'm moving from Apache on Linux to Azure Web Apps and I have a specific url (mysite.com/blog and everything under it) that is configured with a reverse proxy so the end user doesn't know that the content is actually coming from another service.
I'm sure I can do this within Web Apps (which runs on IIS) but I can't find any documentation on how to do this. As a backup I'm open to putting another service in front of my Web App.
How can I accomplish this in Azure?
Update: I did try using another service - Functions. My architecture looks like this:
This works in production but I'm hitting snags in development. /blog may or may not work depending on the entry point. In prod, our DNS will be configured so mysite.com points to mysite-proxy.azurewebsites.net and, therefore, any URI the user hits will work. In dev, however, we may want to browse to hit /blog from the Traffic Manager which will route us to /blog on the webapp which doesn't exist. Same problem, of course, if we go to /blog directly on the webapp. I tried to show these examples on the right side of the diagram.
I would like to find a solution so the webapp itself can handle the /blog proxying and then we can determine whether it's worth the speed and cost tradeoff compared to the existing solution.

Sounds like you want an Application Gateway (caution, costs like $15/day)
The AGW can have multiple listeners against multiple hostnames, including path-based routing.
You will want to add two backends, one for the /blog endpoint and one for the non-/blog stuff. The backends just take the IP or FQDN of the target resource, in this case you will have:
blogBackend: myblog.com
defaultBackend: myWebapp.azurewebsites.net
Then you need to add listeners for your public-facing domain, it would be like:
myHttpListener: port 80, hostname=mywebsite.net
myHttpsListener: port 443, hostname=mywebsite.net
Then you need an HTTP setting
myHttpSetting: protocol=HTTPS, port=443, useWellKnownCACert=Yes, HostnameOverride=Yes,pick from backend target
Then you need rules, one for http=>https redirect, and the other for handling the pathing
myRedirectRule: type=basic, listener=myHttpListener, backendtargettype=redirection, targettype=listener, target=myHttpsListener
myRoutingRule: type=path-based, listener=myHttpsListener, targettype=backendpool, target=defaultBackend, httpSetting=myHttpSetting, pathRules=
path=/* name=root backendpool=defaultBackend
path=/blog name=blog backendpool=blogBackend
You can create additional http settings and assign them to the path rules to change the behaviour of the reverse proxy. For example, you can have the user's URL be https://mywebsite.net/blog, but have the path stripped on the request to the blog so the request looks like myblog.com instead of myblog.com/blog
There's a lot of tiny parts, but the app gateways can handle multiple applications at scale. Biggest thing is to watch out for the cost since this is more of an enterprise solution.
I have 2 web sites installed on the same IIS server. I need them both to listen on port 443 with HTTPS. I want them to use different application pools and be able to stop and start one without affecting the other. The clients of these websites are not able to configure the host header that they use in their HTTP requests.
Is there a solution? I have been trying to use IIS Rewrite rules. I have one website deployed on port 443 and the other on some unusual port. I tried setting up a URL rewrite on the first one that did a rewrite (not a redirect) to an absolute URL referencing the 2nd site on the unusual port. This always seems to produce an HTTP 404 response.
I can't do a redirect because the client gets redirected to the unusual port and the client is not allowed to make internet requests to non-standard ports.
I believe I am using IIS 6.2, that's what is says in the Help about in IIS MAnager
What options do I have?
It is not possible to rewrite to different applications in IIS, especially if they are in different application pools. Your only option is redirect if you want to do it simply using URL Rewrite.
Another alternative is to use ARR (Application Request Routing) and then proxy the call to the actual site depending on rules, this has also the advantage that sites could be in different machines or in the same one, and give you more flexibility. Obviously it does come with more complexity.
Is there any way to have multiple, independent iis websites that all use the same URL base path?
I have a Web API application that contains http webservices grouped by domain (order, product, shipping, etc...). I want to break those domains into individual API applications so that I can deploy them individually. The only problem is that I don't know how I'd deploy these to iis without having a different url path for each API application.
For example, currently (since every web service is in a single WEB API application), if i want to use the order API, i simply use
http://localhost/api/order/{order-id}
If i were to break apart the application into smaller web applications (1 per domain), is there any way i can continue to use
http://localhost/api
as my base path? Or will I have to use something like:
http://localhost/OrderApi/order/{order-id}
Reverse Proxying / Url Rewriting to different ServiceStack instances
An elegant option is to separate them into distinct Services and conceptually have them appear under the same url structure by using a reverse proxy or rewrite rules in IIS which will let you have different top-level paths mapped to different independent ServiceStack instances, e.g:
http://api.domain.com/productA -> http://localhost:8000
http://api.domain.com/productB -> http://localhost:8001
http://api.domain.com/productC -> http://localhost:8002
Our company has two sites
www.mysite.com -- Wordpress site
www.mysite.com/portal -- asp.net mvc site
We want to move the wordpress site (www.mysite.com) to Azure and the other site stays local. We need to url stay the same. How can we achieve this?
Since you state that you need the URL to stay the same, this can be achieved through a reverse proxy. You would set up a web server (typically nginx or IIS) answering on www.mysite.com.
This web server would have reverse proxy rules to forward requests for /portal to your on-premises server (in a given, non-public IP and port) and all other requests to another web server running WordPress (on the same server/cluster that runs the reverse proxy, or a separate one), also with a given IP and port.
All user requests, then, would reach the reverse proxy, that would serve them from cache if possible, or forward them to the internal web servers, and send the response back to the user, transparently. Notice that this is an internal operation, not a redirect response.
Although this setup is more complex than the simpler solution of using different subdomains (www.mysite.com for website and portal.mysite.com for application), it comes with certain advantages that are described in the referenced Wikipedia article, such as security and acceleration.
Alternatively you could create separate subdomains as described above, and use a redirect rule to redirect requests for www.mysite.com/portal/x to portal.mysite.com/x. In this case, the user would see the updated URL in their browser, but the old ones would still work.
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.
