regex problem

[alahori]

Hi all, I am using mnogosearch-3.1.19.. The problem i am facing is of session ... my url are like http://mysite/mypage.php?sessionid=session_string   since whenever indexer runs the session assigned to it is different and for same page different urls are created ... and finally gives me multiple search results for same text...   let me clear it, say at time X url is http://mysite/mypage.php?sessionid=session_stringX   and at time X+Hours url for the same text is http://mysite/mypage.php?sessionid=session_stringX+Hours   The solution of this what i think is to remove the session portion from the url while indexing ..Docs says to use ReverseAlias. When I use this with proper regex indexer gives error at this line. I used this expression ReverseAlias regex(http://[^&]*)&PHPSESSIONID=[^&]*(.*) $1$2   I checked the lots of documentation and mailing lists, Finally came here with problem Please Help   Thanx in Advance Ashish
