MDSWS

Multirequest allows you to send several inquiries at once, and the possibility of combining them (the equivalent of SQL' from UNION') Multirequestu aim is to minimize delays due to data or make multiple connections over the network. Multirequest performance is the same as in the case of multiple queries sent in a queue of requests, currently maximum number is 10 (Conditions of the union also counts as a separate question)

To send several inquiries <request> simply duplicate sections for each query with mandatory attribute @id (up to 11 alphanumeric characters) that will allow you to locate it in response. for example, to ask both of filters and offers the operator ITAK simply send
