Less one slash URI Path

Today, Microsoft did not follow the standard of the practice toss a bit, write a blog to complain about.

Let's take a look at the standard definition (link) for the URI structure of the IETF (Internet Engineering Task Force):

Note that the path section (/over/there) above is a slash that contains the beginning.

Microsoft's eyes, however, are less the beginning of this slash---over/there.

When you use Microsoft's IIS Url Rewrite module to write a matching rule, you must exclude the beginning of this slash.

When you write routing rules using Routes.maproute in asp.net mvc, you must exclude the beginning of this slash.

When you face such a URI (http://www.cnblogs.com/), the matching rule is written as ^$.

If you leave aside the standard, it is more reasonable to use intuition only, "/over/there" is better than "Over/there", because by the beginning of the "/" can intuitively know that starting from the root path, "Over/there" gives a person's intuition is a relative path.

If you're a programmer who uses Microsoft's platform for a long time, it may not be deep because of the habit, but if you're a programmer who has turned from a non-Microsoft platform, you're not used to it.

And I was tossing today not because from a non-Microsoft platform to Microsoft platform, but from Helicon Tech isapi_rewrite to Microsoft's IIS Url Rewrite module.

Today after migrating a site from IIS 7.5 (Windows Server 2008 R2) to IIS 8.0 (Windows Server 2012) (Incidentally, the IIS 8.0 is not compatible with the IIS 7.5 configuration file), it is found that Isapi_ Rewrite can cause IIS application pool crashes (503 errors) under some overriding rules and can only use IIS Url Rewrite module instead.

IIS URL Rewrite module supports importing URL rewrite rules from Isapi_rewrite httpd.ini configuration files, but because the URI path in Microsoft's eyes is unique, it has to modify each rule. Before, blog site was this problem toss, today again be toss, in the mind is very uncomfortable, so write blog chest!

As a programmer who has been using Microsoft platform for a long time, I am not accustomed to a slash in the URI path even if I do not encounter this URL rewrite problem!

In Microsoft's URL Rewrite module's Help document URL Rewrite module Configuration reference, you can find the URI standard in Microsoft's mind:

For a HTTP URL in this form:http (s)://
