.SH "Detailed Description"
.PP 
Basic support for HTTP serving\&. 

As Libevent is a library for dealing with event notification and most interesting applications are networked today, I have often found the need to write HTTP code\&. The following prototypes and definitions provide an application with a minimal interface for making HTTP requests and for creating a very simple HTTP server\&. 
.SH "Macro Definition Documentation"
.PP 
.SS "#define EVHTTP_URI_NONCONFORMANT   0x01"

.PP
Tolerate URIs that do not conform to RFC3986\&. Unfortunately, some HTTP clients generate URIs that, according to RFC3986, are not conformant URIs\&. If you need to support these URIs, you can do so by passing this flag to evhttp_uri_parse_with_flags\&.
.PP
Currently, these changes are: 
.PD 0

Nonconformant URIs are allowed to contain otherwise unreasonable characters in their path, query, and fragment components\&.
