Url rewriting in windows azure

These conditions are based on the request and response properties request, header, response header and server variables. You use rewrite actions to specify the URL, request headers or response headers that you want to rewrite and the new value to which you intend to rewrite them to.

The value of a URL or a new or existing header can be set to these types of values:. You can use rewrite conditions, an optional configuration, to evaluate the content of HTTP S requests and responses and perform a rewrite only when one or more conditions are met.

The application gateway uses these types of variables to evaluate the content of requests and responses:. You can use a condition to evaluate whether a specified variable is present, whether a specified variable matches a specific value, or whether a specified variable matches a specific pattern. Application Gateway uses regular expressions for pattern matching in the condition. To learn about regular expression syntax, see the Perl regular expressions main page.

To capture a substring for later use, put parentheses around the subpattern that matches it in the condition regex definition. The first pair of parentheses stores its substring in 1, the second pair in 2, and so on. You may use as many parentheses as you like; Perl just keeps defining more numbered variables for you to represent these captured strings.

Some examples from ref :. The case of the condition variable needs to match case of the capture variable. For example, if my condition variable is User-Agent, my capture variable must be in the case of User-Agent i. If my condition variable is defined as user-agent, my capture variable must be in the case of user-agent i.

If you want to use the whole value, you should not mention the number. Application Gateway uses server variables to store useful information about the server, the connection with the client, and the current request on the connection. Examples of information stored include the client's IP address and the web browser type. Server variables change dynamically, for example, when a new page loads or when a form is posted. You can use these variables to evaluate rewrite conditions and rewrite headers.

Application Gateway supports the following server variables for mutual authentication scenarios. Use these server variables the same way as above with the other server variables.

To configure a rewrite rule, you need to create a rewrite rule set and add the rewrite rule configuration in it. Request routing rule association: The rewrite configuration is associated to the source listener via the routing rule. When you use a basic routing rule, the rewrite configuration is associated with a source listener and is a global header rewrite. When you use a path-based routing rule, the rewrite configuration is defined on the URL path map. In that case, it applies only to the specific path area of a site.

You can create multiple rewrite sets and apply each rewrite set to multiple listeners. But you can apply only one rewrite set to a specific listener. Rewrite Condition : It is an optional configuration. If you associate more than one condition with an action, the action occurs only when all the conditions are met. In other words, the operation is a logical AND operation.

Enabling 'Re-evaluate path map' is not allowed for basic request routing rules. This is to prevent infinite evaluation loop for a basic routing rule.

Thanks for this great feedback. Really appreciate it. I'm aware that if we had been based on MVC, this would be much easier. I understand you are not using MVC. I remember when I was evaluating MVC in the early days when we were trying to decide on an architecture. Thinking of those days gives me a headache.

One question, is ignoring the human readable hyphenated title considered "best practice"? In other words, should we be relying on an ID, or should we implement something that guarantees each title is unique, and just use that instead? There are clearly successful websites that use an ID and ignore the hyphenated slug. It would certainly be harder to remember the url, though, with a dependency on an integer ID, but I doubt people will be memorizing URLs about Paris Hilton winning the Nobel peace prize in any event.

Either way, you could always expand on the routing resolution after your app is already working — smartcaveman. Good point. Although if Paris Hilton were, by some miracle, to win the Nobel Peace Prize, then all bets would be off! It would become the hottest URL on the Internet!

Stuart Stuart Thanks for the real-world example. Seems like doing this is going to be easier than I thought. I had some trouble doing this against my localhost server 6 months ago when I first gave it a whirl, but now that we have our production and staging servers up on Azure, I bet things will be go a lot smoother.

If you have problems on your localhost server, then maybe give IIS Express a whirl. And having used Azure, I'll take your money on that bet ; — Stuart. For more information and to download the module, see the URL Rewrite extension home page. All rewrite rules in your ApplicationHost.
