From d9671919ed9d0cbdc71f4e83d4cc11d200482226 Mon Sep 17 00:00:00 2001 From: Ingela Anderton Andin Date: Wed, 27 May 2015 09:01:07 +0200 Subject: inets: Add customize option Many HTTP headers are optional, and it could be desirable for the server to filter and maybe even alter them without replacing the mod_* modules that generate/process them. Add new behaviour httpd_custom_api with default implementation in httpd_custom.erl. Add behaviour module in 18 as then we can specify optional callbacks. --- lib/inets/test/httpc_SUITE.erl | 23 +++++++++++-------- lib/inets/test/httpd_SUITE.erl | 51 ++++++++++++++++++++++++++++++++++++------ 2 files changed, 58 insertions(+), 16 deletions(-) (limited to 'lib/inets/test') diff --git a/lib/inets/test/httpc_SUITE.erl b/lib/inets/test/httpc_SUITE.erl index 21be7862cb..4b1c6931d2 100644 --- a/lib/inets/test/httpc_SUITE.erl +++ b/lib/inets/test/httpc_SUITE.erl @@ -1260,7 +1260,9 @@ dummy_server_init(Caller, ip_comm, Inet, _) -> {max_header, ?HTTP_MAX_HEADER_SIZE}, {max_version,?HTTP_MAX_VERSION_STRING}, {max_method, ?HTTP_MAX_METHOD_STRING}, - {max_content_length, ?HTTP_MAX_CONTENT_LENGTH}]]}, + {max_content_length, ?HTTP_MAX_CONTENT_LENGTH}, + {customize, httpd_custom} + ]]}, [], ListenSocket);
