I'm trying to log reffering urls to a site I have to look out for, but it only seems to catch them if the referer is from the same window (ie like if you click a link from google), but if its a site which opens links in a new window (like when you click a link on a post here, it opens a new window) it won't catch the referer.

I'm guessing its because its a new window, it doesnt tag it maybe...

I'm using this method to get the referer...

Request.ServerVariables("HTTP_REFERER")

Any other ideas?

Thought I best include the whole code...

code:
<%

Dim blnValidEntry



blnValidEntry = True



If not IsEmpty(Session("LogIn")) then blnValidEntry = False



If Left(Request.ServerVariables("HTTP_REFERER"), 31)="http://stnicholas-school.org.uk" Then

	blnValidEntry = False

End If



If Left(Request.ServerVariables("HTTP_REFERER"), 35)="http://www.stnicholas-school.org.uk" Then

	blnValidEntry = False

End If



If Request.ServerVariables("HTTP_REFERER") = "" Then

	blnValidEntry = False

End If



If blnValidEntry Then

	Const ForAppending = 8

	Const Create = True

	Dim FSO

	Dim TS

	Dim LogFileName

	Dim strLog

	

	LogFileName = Server.MapPath("logs\referers.htm")

	

	Set FSO = Server.CreateObject("Scripting.FileSystemObject")

	Set TS = FSO.OpenTextFile(LogFileName, ForAppending, Create)

	strlog = "<table width=""100%""  border=""1"" cellspacing=""0"">"

	strlog = strlog & "<tr>"

	strlog = strlog & "<td width=""20%"" class=""style5"">" & NOW() & "</td>"

	strlog = strlog & "<td width=""20%"" class=""style5"">" & Request.ServerVariables("URL") & "?" & Request.ServerVariables("QUERY_STRING") & "</td>"

	strlog = strlog & "<td width=""20%"" class=""style5""><a href=""" & Request.ServerVariables("HTTP_REFERER") & """ target=""_blank"">" & Request.ServerVariables("HTTP_REFERER") & "</a></td>"

	strlog = strlog & "<td width=""40%"" class=""style1 style4"">" & Request.ServerVariables("HTTP_USER_AGENT") & "</td>"

	strlog = strlog & "</tr></table>"

	

	TS.write strlog

	TS.Writeline ""

	

	Session("LogIn") = "yes"

	Set TS = Nothing

	Set FSO = Nothing

	

End If

%>

no, when a new window is opened, there isnt a referer heading

Only way to do it mate, if you want to log where there from is by IP address, then do a DNS on them and do it that way

Atleast you will know what ISP there using, but thats about it mate

Impossible - if the browser isn't providing this variable then you've no way of forcing it to be there. I'm sure some of the more obscure browsers can be configurered to turn it off as well - you'd never see it from these.

Also, why are you logging HTML tags!?

Either write them to a db or csv or something, then write a script to traverse the data and make you a page. Anything else gives you huge web pages very quickly.

put it in anyways mate and tell the head that its impossible etc

Also, btw mate, that code can be written alot simpler, by doing:

code:


<%

Dim strReferer

strReferer = Request.ServerVariables("HTTP_REFERER")



If strReferer <> "http://stnicholas-school.org.uk" or strReferer <> "http://www.stnicholas-school.org.uk" or strReferer <> "" or not IsEmpty(Session("LogIn")) then

	Const ForAppending = 8

	Const Create = True

	Dim FSO

	Dim TS

	Dim strLog



	Set FSO = Server.CreateObject("Scripting.FileSystemObject")

	Set TS = FSO.OpenTextFile(Server.MapPath("logs\referers.htm"), ForAppending, Create)

	strlog = "<table width=""100%""  border=""1"" cellspacing=""0"">"

	strlog = strlog & "<tr>"

	strlog = strlog & "<td width=""20%"" class=""style5"">" & NOW() & "</td>"

	strlog = strlog & "<td width=""20%"" class=""style5"">" & Request.ServerVariables("URL") & "?" & Request.ServerVariables("QUERY_STRING") & "</td>"

	strlog = strlog & "<td width=""20%"" class=""style5""><a href=""" & Request.ServerVariables("HTTP_REFERER") & """ target=""_blank"">" & Request.ServerVariables("HTTP_REFERER") & "</a></td>"

	strlog = strlog & "<td width=""40%"" class=""style1 style4"">" & Request.ServerVariables("HTTP_USER_AGENT") & "</td>"

	strlog = strlog & "</tr></table>"

	

	TS.write strlog

	TS.Writeline ""

	

	Session("LogIn") = "yes"

	Set TS = Nothing

	Set FSO = Nothing

	

End If

%>

although im not sure how many "or" statments you can use

so it might not work, but im 90% sure that the way i just chopped it, it will

its probably because it nice and easy mate

Although yea, i agree, loading a 10+mb html page isnt the nicest thing in the world

TBH, there are loads of ways to do it, like dumping the data into a db etc But then you could add a part where it will compare the sent HTTP_REFERER head to whats in the database (storage solution) then if it isnt in the db then it will add it, otherwise it will increase a value next to the already existing HTTP_REFERER website string. But then you start to write a full blown website logger and if thats the case you might as well just download a freebie logger...plenty of them and will offer loads more info

I wouldn't check what's already in there on the write.

Just log the line, the use a grouping query to do the counting. That's how the post distribution thing in your profile works, group by forum and order by the count, descending. There's also a bit of maths in there to divide the count figure by post total and give percentage but the SQL is identical.

But yeah, if you're going to go those lenths....
