We are using htaccess on our server and are getting random garbled urls that return 404 errors listed in Google webmaster tools. These urls are rewriting incorrectly because they contain a slash "/" in one of the variables. A sample url that has the problem is: http://www.oehq.com/acdelco-parts-for_GMC_1996_P35/P3500-VAN_2739_2280_CLU-ACCUM-PSTN-INR-SEAL-3RD_37.htm here is the rewrite rule I am using RewriteRule ^acdelco-parts-for_([^_]+)_([^_]+)_([^_]+)_([^_]+)_([^_]+)_([^_]+)_([^_]+)\.htm acdelco-parts-for.cfm?vmake=$1&vyear=$2&vmodel=$3&vmodid=$4&vengine=$5&vcat=$6&vsubcat=$7 [NC,L] The problem appears to be with the "/" in the 3rd argument. the "/" cause the rewrite to fail. Can anyone help me create a rewrite expression that will replace all occurences of "/" with a "-" in a string of the 3rd argument? For Example: http://www.oehq.com/acdelco-parts-for_GMC_1996_P35-P3500-VAN_2739_2280_CLU-ACCUM-PSTN-INR-SEAL-3RD_37.htm Thanks
Does it happen only in the 3rd argument? If yes, then adding one additional line of rule beside the one you already have would do the trick. Something like this maybe: RewriteRule ^acdelco-parts-for_([^_]+)_([^_]+)_([^_]+)/([^_]+)_([^_]+)_([^_]+)_([^_]+)_([^_]+)\.htm acdelco-parts-for.cfm?vmake=$1&vyear=$2&vmodel=$3-$4&vmodid=$5&vengine=$6&vcat=$7&vsubcat=$8 [NC,L] Code (markup): Do not modify your initial rule. Just add this one as well after your original one. If this was happening only with a 3rd variable, then this will fix the problem. If the slash is appearing in the other variables as well, then the best thing to do would be to just rewrite your scripts to replace the slash / with a - at the time of URL generation. So you won't even have urls with / in the field variables, and the 404's would drop from the Google after some time, as they would no longer appear in your web site pages.
