+# pecl/http v2
+
+[![Build Status](https://travis-ci.org/m6w6/ext-http.svg?branch=master)](https://travis-ci.org/m6w6/ext-http)
+
+## About:
+
+Extended HTTP support. Again. 
+
+* Introduces the http namespace.
+* PHP stream based message bodies.
+* Encapsulated env request/response.
+* Modular client support.
+
+## Installation:
+
+This extension is hosted at [PECL](http://pecl.php.net) and can be installed with [PEAR](http://pear.php.net)'s pecl command:
+
+    # pecl install pecl_http
+
+## Dependencies:
+
+pecl/http depends on a number of system libraries and PHP extensions for special features.
+
+#### Required system libraries:
+
+The following system libraries are required to build this extension:
+
+=zlib=
+       Provides gzip/zlib/deflate encoding.  
+       Minimum version: 1.2.0.4  
+       Install on Debian: `apt-get install zlib1g-dev`
+
+
+#### Optional system libraries:
+
+The following system libraries are optional and provide additional features:
+
+=libidn=
+       Provides IDNA support in URLs.  
+       Minimum version: none  
+       Install on Debian: `apt-get install libidn11-dev`
+
+=libidn2=
+       Provides IDNA support in URLs (fallback if libidn is not available).  
+       Minimum version: none  
+       Install on Debian: `apt-get install libidn2-0-dev`
+
+=libicu=
+       Provides IDNA support in URLs (fallback if libidn is not available).  
+       Minimum version: none  
+       Install on Debian: `apt-get install libicu-dev`
+
+=libcurl=
+       Provides HTTP request functionality.  
+       Minimum version: 7.18.2  
+       Install on Debian: `apt-get install libcurl4-openssl-dev`  
+       Note: There are usually different styles of SSL support for libcurl available, so you can replace 'openssl' in the above command f.e. with 'nss' or 'gnutls'.
+
+=libevent=
+       Eventloop support for the HTTP client.  
+       Minimum version: none  
+       Install on Debian: `apt-get install libevent-dev`
+
+### PHP extensions:
+
+This extension unconditionally depends on the pre-loaded presence of the following PHP extensions:
+
+* raphf
+* propro
+* spl
+
+
+If configured ```--with-http-shared-deps``` (default) it depends on the pre-loaded presence of the following extensions, as long as they were available at build time:
+
+* hash
+* iconv
+* json (only until < 2.4.0)
+
+Please ensure that all extension on which pecl/http depends, are loaded before it, e.g in your `php.ini`:
+
+       ; obligatory deps
+       extension = raphf.so
+       extension = propro.so
+       
+       ; if shared deps were enabled
+       extension = hash.so
+       extension = iconv.so
+       extension = json.so
+       
+       ; finally load pecl/http
+       extension = http.so
+
+## Conflicts:
+
+pecl/http-v2 conflicts with the following extensions:
+
+* http-v1
+* event (only until <= 2.0.3)
+
+## INI Directives:
+
+* http.etag.mode = "crc32b"  
+  Default hash method for dynamic response payloads to generate an ETag.
+
+## Stream Filters:
+
+The http extension registers the ```http.*``` namespace for its stream filters. Provided stream filters are:
+
+* http.chunked_decode  
+  Decode a stream encoded with chunked transfer encoding.
+* http.chunked_encode  
+  Encode a stream with chunked transfer encoding.
+* http.inflate  
+  Decode a stream encoded with deflate/zlib/gzip encoding.
+* http.deflate  
+  Encode a stream with deflate/zlib/gzip encoding.
