filter - How to use paging in a WFS query?

I am running a GetFeature request against a WFS server which does not support to download all data at once. Can I use ogc:PropertyIsGreaterThanOrEqualTo to split the dataset into chunks at download them step by step? I wonder how I can construct the actual URL to include the paging filter. Here is what I tried:

http://example.com/wfs.aspx?request=GetFeature&service=WFS&version=1.1.0 \
&typeName=example:example&maxFeatures=50000 \
&FILTER= \

OBJECTID \
50000

This is not a valid URI though... That's why uri-encoded the filter part:

http://example.com/wfs.aspx?request=GetFeature&service=WFS&version=1.1.0 \
&typeName=example:example&maxFeatures=50000 \    
&FILTER=%3Cogc%3AFilter%20xmlns%3Aogc%3D%22http%3A%2F%2Fwww.opengis.net \
%2Fogc%22%3E%3Cogc%3APropertyIsGreaterThanOrEqualTo%3E%3Cogc%3APropertyName%3EOBJECTID \
%3C%2Fogc%3APropertyName%3E%3Cogc%3ALiteral%3E50000%3C%2Fogc%3ALiteral \
%3E%3C%2Fogc%3APropertyIsGreaterThanOrEqualTo%3E%3C%2Fogc%3AFilter%3E

This actually works. Is there a "nicer" way to do this?
