GZIP in enaio® webclient

enaio® webclient 10.10

enaio® webclient can transfer resources in compressed format. This saves a large amount of bandwidth and therefore increases the speed of enaio® webclient.

Before using compression, please check your network infrastructure and router to ensure compatibility with GZIP-compressed data transmission when processing web requests.

GZIP compression can also be enabled for enaio® appconnector. GZIP compression is enabled for enaio® gateway by default.

Configuring Compression

The configuration is carried out using the following entry in the osweb-prod.yml file located in the \service-manager\config directory:

server:
  compression:
    enabled: true
    mime-types: text/html,text/xml,text/plain,text/css,text/javascript,application/javascript,application/json,image/svg+xml
    min-response-size: 2048 
                                                            

By enabling GZIP compression, files with the corresponding MIME type and a minimum size of 2KB will be compressed and transferred between the 'osweb' microservice and enaio® gateway.

GZIP Compression in enaio® appconnector

It is also recommended that GZIP compression be used in enaio® appconnector. Please check whether all other clients that also request data via enaio® appconnector can handle the compression.

There are two attributes for this in the HTTP connector in the conf\server.xml file of the Tomcat distribution of enaio® appconnector.
