HttpParser (Apache Tomcat 8.5.61 API Documentation)

```
public class HttpParser
extends Object
```
HTTP header value parser implementation. Parsing HTTP headers as per RFC2616 is not always as simple as it first appears. For headers that only use tokens the simple approach will normally be sufficient. However, for the other headers, while simple code meets 99.9% of cases, there are often some edge cases that make things far more complicated. The purpose of this parser is to let the parser worry about the edge cases. It provides tolerant (where safe to do so) parsing of HTTP header values assuming that wrapped header lines have already been unwrapped. (The Tomcat header processing code does the unwrapping.)
