Release Overview : isCOBOL 2023 Release 1 Overview : isCOBOL EIS
isCOBOL EIS
isCOBOL EIS, Veryant’s solution to write web-enabled COBOL programs, is constantly updated to provide more comprehensive web solutions. As of version isCOBOL 2023 R1, the HTTPClient class can set a Proxy server to be used when performing network activity, and a new specific log file has been implemented to log the activity.
 
HTTPClient class
HTTPClient is a class that enables COBOL programs to interact with Web Services and HTTP Servers. This class has been updated with this new method signature:
public void setProxy (String Ip, Int Port)
After invoking this method, the specified proxy server is used for all the following requests performed by the HTTPClient instance.
New configurations have been implemented to trace the HTTPClient activity:
• iscobol.httpclient.logging=true to enable logging
• iscobol.httpclient.logfile=/path/to/logfile to specify the log pathname
The log includes the request date and time, the request content, the response code, the response headers and the response content. If the file already exists, the new content is appended to it.
This is an example of the log content running the installed sample IP2GEO with the two new configuration settings:
