Parse neko stran

Tole lahko v browserju odpreš zmeraj normalno, spodaj je submit forma/knof 'List of species'.
Ne vem kaj to pošlje poleg tega kje je target, nič ?
link1

target link tega knofa, če poskusiš tole odpret v ravno odprtem browserju, ne dela:
link2

če z mojim httpclent, odprem link1 in nato link2 (v isti seji, predvidevam), deluje.

Katerikoli link na link2, klik, npr:
https://italic.units.it/flora/index.php...
tudi ne deluje če ga odpreš v ravno zagnanem browserju.

če se grem z mojim programom

httpclient.get(link1)
httpclient.get(link2)
httpclient.get(link3)

nekako deluje, do link3, s tem, da link3 ne dobim obsežnejšega texta pod prvo sliko (kajpak, ravno ta text me zanima).

Z network debuger ne vidim nič pametnega.

Kakšna ideja ?
