Exclure les robots indésirable : 2 méthodes

[bjp]

Voilà, après quelques recherches et surtout après avoir constaté les limites du fichier robots.txt pour exclure les robots indésirables, j'ai vu qu'il est possible d'inscrire des lignes dans le fichier htaccess.
J'ai trouvé 2 manières dont voici des extraits.

La première façon est semble t il très complète mais donne un fichier htacces de 13 k

La seconde manière est la suivante :

SetEnvIfNoCase User-Agent "^EmailSiphon" bad_bot
SetEnvIfNoCase User-Agent "^EmailWolf" bad_bot
SetEnvIfNoCase User-Agent "^ExtractorPro" bad_bot
SetEnvIfNoCase User-Agent "^CherryPicker" bad_bot
SetEnvIfNoCase User-Agent "^NICErsPRO" bad_bot
SetEnvIfNoCase User-Agent "^Teleport" bad_bot
SetEnvIfNoCase User-Agent "^EmailCollector" bad_bot
SetEnvIfNoCase User-Agent "^LinkWalker" bad_bot
SetEnvIfNoCase User-Agent "^Zeus" bad_bot

<Limit GET POST>
Order Allow,Deny
Allow from all
Deny from env=bad_bot
</Limit>

D'après vous, quelle manière est la meilleure ? La première solution avec un fichier de 13 k n'allourdit elle pas trop un site ?

 

[WebRankInfo]

mon .htaccess fait 19Ko : trouvez-vous la navigation si lente que ça ? je ne sais pas s'il y a une limite raisonnable

 

[bjp]

Non, votre site est rapide. Mais d'après vous, quelle forme parmi celles que je propose devrait prendre le htaccess ?

 

[Qaghan]

Je ne porte pas de jugement mais la premiere methode ne peut etre utilisee que sur les hebergements supportant l'UR, alors que la deuxieme semble plus universelle...

---

L'utilisation du joker * dans la definition des expressions regulieres des mauvais bots permet quelques petites optimisations:

RewriteCond %{HTTP_USER_AGENT} .*WebStripper* [OR] 
RewriteCond %{HTTP_USER_AGENT} .*WebStripper/2.09* [OR]

La deuxieme ligne est superflue car tout UA satisfaisant celle-ci satisfait aussi la premiere...

---

Quoiqu'il en soit si je devais sciemment programmer un robot irrespectueux (dont l'ignorance du fichier robots.txt est un symptôme), je m'arrangerai pour generer des UA aleatoires...

Olivier,

 

[jmarc]

Salut

pouvez vous m'oter un doute ?
RewriteCond %{HTTP_USER_AGENT} ^WebStripper$ [OR]
et
RewriteCond %{HTTP_USER_AGENT} .*WebStripper* [OR]

revient au même non ?
(pas facile les regex)

 

[milkiway]

ça sert à quoi d'exclure un bot ?

 

[Kmacleod]

RewriteCond %{HTTP_USER_AGENT} .*WebStripper* [OR]

Cette ré-écriture est générique, c'est à dire que tu peux exclure aussi l'agent qui evoluerai pour devenir WebStripper-v2. Avec le première ecriture, le robot ne serait pas arrété.

=>milkiway
Exclure un robot permet de limier la consommation de bande passante ou de hits pour les robots qui n'apportent rien au site (langue differente ou robot mal intentionnés)

 

[milkiway]

robot mal intentionnés

Il y a des robots qui nous veulent du mal !?
Il faut mettre ce fichier .htaccess pour éviter ça ?
Les 13 ko les utilisateurs du site doivent les charger ? Si c'est beaucoup trop !

 

[Kmacleod]

13 ko est un peu beaucoup, d'autant qu'il y a des robots qui ne passent pas sur tout les sites.
Le mieux est de mettre à jour le fichier en fonction de ce que l'on voit dans les logs, ou dans les stats.
Interdire certains robots de mail ne sert à rien, si par exemple il n'y a pas d'adresse mai sur son site, ou si les adresses mail sont déjà protégées.

 

[jmarc]

Merci pour ce complément d'info

bonne journée

 

[milkiway]

Adresses email protégées ?

 

[Kmacleod]

Adresses email protégées ?

Oui en cryptant une adresse email

D'autres solutions sont possbiles auprès des pro de la sécurité de webrankinfo, qui ont surement d'autres bons liens dans leur favoris.
Sinon essaye d'autres discussions de solution anti spam sur webrankinfo

 

[milkiway]

ok merci je comprends
mais pour les mails je n'utilise que le mail(); donc pas de risque

 

[stephanelhomme]

Bonjour,
Comme le dit si bien Qaghan, il suffit que les robots changent d'UA (un UA vide par exemple) pour contourner le restrictions du fichier htaccess.... Y a pas une autre methode plus efficace pour determiner si un robot arrive (peut etre avec un bout de code php ) ?
