Compression Techniques

Use

If you want to send large quantities of data, we recommend that you compress it first to keep the transports as small as possible.

Example

The example below shows how you might use data compression.

                    


                    
DATA: html_body TYPE string.
                    
…
                    
IF compress NE space.
                    


                    
CALL METHOD server->response->set_header_field(
                    
name = 'Content-Type'
                    
value = 'text/html' ).
                    
*

CALL METHOD server->set_compression
                    
EXPORTING
                    
options = if_http_server=>co_compress_in_all_cases
                    
EXCEPTIONS
                    
compression_not_possible = 1
                    
OTHERS = 2.
                    
IF sy-subrc <> 0.
                    
CONCATENATE
                    
'<html>'
                    
'<body>'
                    
'Compress nicht möglich '(001) '</br>'

INTO html_body.
                    
ELSE.
                    
CONCATENATE '<html>'
                    
'<body>'
                    
'Compress erfolgreich '(001) '</br>'
                    
'</body>'
                    
'</html>'
                    
INTO html_body.
                    
ENDIF.
                    
*
                    
* if compression could be activated the body will be transferred
                    
* as gzip compressed body
                    
*
                    
CALL METHOD server->response->set_cdata( data = html_body ).
                    
ENDIF.
