There are two ways you can do that - depending on what you want:

1) You can use the HTXParse stream (look into HTXParse.html). This provides a 
unlimited buffering of the input. This is the approach used by Arena that has 
its own HTML parser.

2) You can use the HTBufWrite stream in the HTConLen module. This stream 
provides a max size buffer. This is used, for example, when calculating 
content length of a document. You can see an example of this in the Line Mode 
Browser.
