| Prévoir des commandes en plusieurs mots clés. |
| Par exemple : |
| |
| timeout connection XXX |
| connection scale XXX |
| |
| On doit aussi accepter les préfixes : |
| |
| tim co XXX |
| co sca XXX |
| |
| Prévoir de ranger les combinaisons dans un tableau. On doit même |
| pouvoir effectuer un mapping simplifiant le parseur. |
| |
| |
| Pour les filtres : |
| |
| |
| <direction> <where> <what> <operator> <pattern> <action> [ <args>* ] |
| |
| <direction> = [ req | rsp ] |
| <where> = [ in | out ] |
| <what> = [ line | LINE | METH | URI | h(hdr) | H(hdr) | c(cookie) | C(cookie) ] |
| <operator> = [ == | =~ | =* | =^ | =/ | != | !~ | !* | !^ | !/ ] |
| <pattern> = "<string>" |
| <action> = [ allow | permit | deny | delete | replace | switch | add | set | redir ] |
| <args> = optionnal action args |
| |
| exemples: |
| |
| req in URI =^ "/images" switch images |
| req in h(host) =* ".mydomain.com" switch mydomain |
| req in h(host) =~ "localhost(.*)" replace "www\1" |
| |
| alternative : |
| |
| <direction> <where> <action> [not] <what> [<operator> <pattern> [ <args>* ]] |
| |
| req in switch URI =^ "/images" images |
| req in switch h(host) =* ".mydomain.com" mydomain |
| req in replace h(host) =~ "localhost(.*)" "www\1" |
| req in delete h(Connection) |
| req in deny not line =~ "((GET|HEAD|POST|OPTIONS) /)|(OPTIONS *)" |
| req out set h(Connection) "close" |
| req out add line "Server: truc" |
| |
| |
| <direction> <action> <where> [not] <what> [<operator> <pattern> [ <args>* ]] ';' <action2> <what2> |
| |
| req in switch URI =^ "/images/" images ; replace "/" |
| req in switch h(host) =* ".mydomain.com" mydomain |
| req in replace h(host) =~ "localhost(.*)" "www\1" |
| req in delete h(Connection) |
| req in deny not line =~ "((GET|HEAD|POST|OPTIONS) /)|(OPTIONS *)" |
| req out set h(Connection) "close" |
| req out add line == "Server: truc" |
| |
| |
| Extension avec des ACL : |
| |
| req in acl(meth_valid) METH =~ "(GET|POST|HEAD|OPTIONS)" |
| req in acl(meth_options) METH == "OPTIONS" |
| req in acl(uri_slash) URI =^ "/" |
| req in acl(uri_star) URI == "*" |
| |
| req in deny acl !(meth_options && uri_star || meth_valid && uri_slash) |
| |
| Peut-être plus simplement : |
| |
| acl meth_valid METH =~ "(GET|POST|HEAD|OPTIONS)" |
| acl meth_options METH == "OPTIONS" |
| acl uri_slash URI =^ "/" |
| acl uri_star URI == "*" |
| |
| req in deny not acl(meth_options uri_star, meth_valid uri_slash) |
| |
| req in switch URI =^ "/images/" images ; replace "/" |
| req in switch h(host) =* ".mydomain.com" mydomain |
| req in replace h(host) =~ "localhost(.*)" "www\1" |
| req in delete h(Connection) |
| req in deny not line =~ "((GET|HEAD|POST|OPTIONS) /)|(OPTIONS *)" |
| req out set h(Connection) "close" |
| req out add line == "Server: truc" |
| |
| Prévoir le cas du "if" pour exécuter plusieurs actions : |
| |
| req in if URI =^ "/images/" then replace "/" ; switch images |
| |
| Utiliser les noms en majuscules/minuscules pour indiquer si on veut prendre |
| en compte la casse ou non : |
| |
| if uri =^ "/watch/" setbe watch rebase "/watch/" "/" |
| if uri =* ".jpg" setbe images |
| if uri =~ ".*dll.*" deny |
| if HOST =* ".mydomain.com" setbe mydomain |
| etc... |
| |
| Another solution would be to have a dedicated keyword to URI remapping. It |
| would both rewrite the URI and optionally switch to another backend. |
| |
| uriremap "/watch/" "/" watch |
| uriremap "/chat/" "/" chat |
| uriremap "/event/" "/event/" event |
| |
| Or better : |
| |
| uriremap "/watch/" watch "/" |
| uriremap "/chat/" chat "/" |
| uriremap "/event/" event |
| |
| For the URI, using a regex is sometimes useful (eg: providing a set of possible prefixes. |
| |
| |
| Sinon, peut-être que le "switch" peut prendre un paramètre de mapping pour la partie matchée : |
| |
| req in switch URI =^ "/images/" images:"/" |
