Manipulates a request's URI. It can strip path prefix/suffix or replace substrings on the whole URI.
This directive is distinct from [`rewrite`](rewrite) in that `uri`_partially_ changes the URI, rather than setting it to something completely different as `rewrite` does. While `rewrite` is treated specially as an internal redirect, `uri` is just another handler.
## Syntax
```
uri [<matcher>] strip_prefix|strip_suffix|replace \
<target> \
[<replacement> [<limit>]]
```
- The first (non-matcher) argument specifies the operation:
- **strip_prefix** strips a prefix from the path, if it has the prefix.
- **strip_suffix** strips a suffix from the path, if it has the suffix.
- **replace** performs a substring replacement across the whole URI.
- **<target>** is the prefix, suffix, or search string/regular expression. If a prefix, the leading forward slash may be omitted, since paths always start with a forward slash.
- **<replacement>** is the replacement string (only valid with `replace`).
- **<limit>** is an optional limit to the maximum number of replacements (only valid with `replace`).
