无法理解Apache的文档

Question

I am having trouble understanding what UriHttpRequestHandlerMapper as written about in the documentation here .

The documentation says that it:

Maintains a map of HTTP request handlers keyed by a request URI pattern. Patterns may have three formats:
*
*<uri>
<uri>*

It doesn't explain what these patterns actually mean. What do the stars do? How do you actually use this?

I have not been able to find any snippets on the internet.

Answer 1

1. * means match any request
2. *<uri> means match any request that ends with what is specified, eg *.jpg
3. <uri>* means match any request that starts with what is specified, eg http://host/application/*
