HTTP 307 redirect

Created by Jerry Wang on Jun 07, 2014

在browser里输入http url之后，

敲回车之后http自动转换成https:

通过httpwatch观察到有一个307 redirect:

通过tcode SMICM 查看ICM server设置:

发现server设置为所有http的request都会自动redirect成https, port number 44356:

debug下面report能找到redirect具体的处理细节:

data(url) = 'http://<XXXX>:50056/sap/bc/srt/wsdl/flv_10002A111AD1/bndg_url/sap/bc/srt/rfc/sap/zweb_add_2/001/s1/b1?sap-client=001'.
data(content) = zcl_crm_cm_tool=>get_text_by_url( conv #( url ) ).

get_text_by_url的方法实现如下:
