Using namespace match uri regex

This section provides some examples of namespace match uri regex use. Change specifics
accordingly.
single quotes (not shown in examples). See
For namespace match uri <uri-prefix>, the regex is written against the absolute path portion
of the URL. For example, given the following URL: http://abc.com:8080/index.html,
/index.html would be the absolute path portion of the URI.

Using namespace match <criteria> precedence
Use namespace <name> match <criteria> precedence to set unambiguous mapping of
incoming GET requests in the case of match <criteria> overlap; precedence can be set on
all match <criteria>. The lower the number, the higher the preference for that namespace;
values 0 (highest precedence) - 10 (lowest precedence) can be used. All namespaces have a
default precedence of 0. For example, consider three URLs and namespaces as follows:
1. http://a.com/abc/def/file1.flv
2. http://a.com/abc/file2.flv
3. http://a.com/pqr/file3.flv
namespace ns1
domain a.com
match uri
origin-server http o1.com
status active
namespace ns2
domain a.com
match uri
origin-server http o2.com
status active
namespace ns3
domain a.com
match uri
origin-server http o3.com
status active
All three URLs match namespace ns3 set domain (a.com) and match uri / (slash). In order to
ensure that match uri #1 (/abc/def) maps to ns1 and not ns3, set the precedence value.
