[SR-Users] Search Un-Register Expires header

Hi, I find a problem when I try to search the header "Expires" with value 0. At my kamailio.cfg the configuration is: if ( search_hf("Expires", ":0@", "a") ) { xlog("L_INFO", "Encontrado expires 0 ($rm)"); } This way find nothing. I test with 0 (no wildcards regular expression), but this make matches in any Register with header Expires content 0. Example: ... if ( search_hf("Expires", "0", "a") ) .... I saw some people control expires=0 at contact header, but not my case. Example: if (search("expires=0")) { xlog("L_INFO", "Encontrado expires 0 ($rm)"); } Regards, -- Emilio Soler emiliosoler(a)gmail.com
