Hi Rosh,

Is this capacity limited to v5 or is this also possible in v4 ?

There's lots of existing MQL4 code for retrieving textual responses from web servers, e.g. https://www.mql5.com/en/code/8435. A little less code for sending data, but that's much the same principle.

It's a bit daft that retrieving a textual response from a web server requires 4 lines of code in a Javascript environment, 4 lines of code in an ActiveX environment, and 4 to 6 lines of code in a .NET environment, but requires 9,732,651 lines of code in an MT5 environment. Retrieving data from a web server is a very frequently asked question about MQL4, and it's a mystery why the the MT5 platform doesn't therefore provide built-in support for it - even if there were to be a security setting preventing its use without user consent.
