V obshchem, zastavili vy menya-taki proinstallit' vash kod i posmotret', chto on delaet :-) Na moj vzglyad, ideya v korne nevernaya, potomu chto:
a) Kak ya uzhe napisal, poiskovik, indeksiruya "razbivochnye" stranitsy, vosprimet vash "all" kak duplicated content.
b) Vash kod "slepo" otobrazhaet VSE vozmozhnye soobshcheniya na odnoj stranitse - kak naschet togo, esli tema soderzhit 100, 200, 2000 soobshchenij? EHto vovse ne redkie primery. Poiskovik takoj stranitsej zakhlebnetsya i ne budet ee vsyu indeksirovat', tak chto pomimo duplicated content vy poluchite eshche i minus za gromozdkij razmer. Da eshche vam i traffika nakrutyat ogo-go.
V vysheupomyanutom primere ot Team vse-taki ispol'zuetsya bolee ratsional'nyj sposob razbivki - po 100 soobshchenij (ehto kol-vo, razumeetsya, mozhno izmenit'). Pod "extra"-razbivkoj stranits ya podrazumevayu sleduyushchee. Naprimer, u vas est' stroka razbivki, kotoraya vyglyadit tak:
Esli vklyuchen $mod_rewrite, to URL dlya ehtikh stranits dolzhny byt', naprimer, takie:
[1] - 8_355_0.html
[2] - 8_355_1.html
[3] - 8_355_2.html
[4] - 8_355_3.html
Esli vy vstavlyaete extra-pagination kod, privedennyj Team i popravlennyj mnoj, to URL dolzhny byt' takie:
. 1 . 2 . >> Extra Pagination
[1] - index.php?alltopics=100&act
ion=vthread&forum=8&topic=355&page=0
[2] - index.php?alltopics=100&action=vthread&forum=8&topic=355&page=1
i tak dalee... T.e. razbivka "po umolchaniyu" prevrashchaetsya v ehkstra-razbivku po "mnogo" soobshchenij, pri ehtom razbivka kak takovaya sokhranyaetsya, no dlya nee stavitsya tehg NOINDEX,NOFOLLOW. YA ehto poproboval v nashej teme "Your impressions and wishes", gde bolee 100 soobshchenij, ehto rabotaet kak nado.
Po povodu "redirect if visiting old URLs" - ne ponimayu, pri chem tam sortirovka. EHto primer dlya pereadresatsii poiskovika so starogo tipa URL na novyj (mod_rewrite), esli na vashikh forumakh iznachal'no stoyal URL vida action=vthread&forum=X&topic=Y&page=Z.
V obshchem-to, ehtot kod tol'ko dlya spetsial'no ozabochennykh. MiniBB avtomaticheski spravlyaetsya s ehtim rezhimom, provereno nami lichno na nashikh zhe forumakh.
