Trace (-T or -TRACE) 
Use the Trace adapter command (-T or -TRACE) to produce a diagnostics file with 
the default name m4http.mtr in the map directory where the adapter is installed. 
The file contains information detailing HTTP adapter activity. 
-TRACE [+][S|V][full_path] 
Option Description 
+ 
Append trace information to the existing log file. 
S 
Summary mode. Default value. Record only minimal 
information in the log file. 
V 
Verbose mode. Record in the log file all activity 
occurring while the adapter is retrieving data. If not 
specified, summary mode assumed. 
full_path 
Create a trace file with the specified name in the 
specified directory. By default, the directory is where 
the map is located and the file name is m4http.mtr.
Note  Because summary mode is the default, using -TRACES provides the same output 
as –TRACE. 
Type (-TY or -TYPE) 
Use the Type adapter command (-TY or -TYPE) to specify the MIME Content-Type 
for the file used in the adapter request. The default type is application/octet-
stream. Refer to Known Limitations for additional information. 
-TYPE content_type 
Option Description 
content_type 
The default content type is application/octet 
stream. You may use other types, but do not 
use compound types such as multipart.
