How to read data from this site?

Hi,

i need to read data from this site: http://adisreg.mfcr.cz/adistc/DphReg?ZPRAC=RDPHI1&id=1&pocet=1&fu=&dic=62412388&OK=+Hledej+ where the number after &dic= is a variable (client number from SAP).

I tried to read its content through RSHTTP20 program (with SAPHTTP as RFC destination) but get this error:

error: NIECONN_REFUSED.

I am able to scrape content from other sites (like http://pinterest.com) - what is the difference here? How can i read this website?

Thanks a lot
