First of all thank you very much for your question. Or course you can do that. The reason why you came across with such problem is that our download link are connected to one particular IP. You can modify that IP as many times as you will need but once you generate a new link, the old one becomes invalid. Here are two possible solutions for your case:

1) You can modify data parameter manually. You can easily find out for what each parameter stand for and modify it manually. The values are 1, 2 or any... as for proxy type it is 1, 2, 3 or 23 and so on.

2) You can generate as many download links as you will need (with different filter parameters) and at the end copy the KEY value from last generated download link (only last KEY is valid) to the all previously generated download links. At the end you will have several links, with the same KEY but different data value.

That option for left for advanced users who need to download different type of proxy servers via single VIP pass. If you have any other question, you can ask us at any time.
