I'm not sure I understand what you are asking. You want to use the string but without the last part? Do you have code you're working with that may help to clarify?

No, without the middle part

?search=&day=&month=4&PAGE=8&latest=all&notfull=&Page=7

All i will know is that there is page= in the middle, but will not know the number.

Why would you have two querystring variables with the same name? This is begging for problems (such as you're currently encountering). Can't you rename the variable? That would be the easiest (and best) solution.

You can make a RegExp and replace.

Here is a code I copied/wrote up

<%@LANGUAGE="VBScript"%>
<%
InitialString = "?search=&day=&month=4&PAGE=8&latest=all&notfull=&Page=7"
eString = "?search=&day=&month=4&PAGE=8&latest=all&notfull=&Page=7"

Set RegExpObj = New RegExp

With RegExpObj
.Pattern = "&Page=\d{1,}"
.IgnoreCase = True
.Global = False
End With

InitialString = RegExpObj.Replace(InitialString, "")

Response.Write InitialString + "<br />"
Response.Write eString

Set RegExpObj = nothing
%>

Funny thing is though that for some reason it's printing funky characters at the "[!]&not[/!]full" part of the string, even before the replace.

Besides that, it replaces removes the first instance of &Page=number fine.

One of these days, I'm really going to have to sit down and figure out RegEx... Nice job, monksnake!

Thanks Chopstik

They really aren't that hard once you look at them. Before I knew much about them at all, it looked like Greek to me.

It looks more Russian to me...

I am not sure if the solution proposed is satisfactory. I would offer a solution for multiple occurence of query on "page" whereby all instances will be deleted except the last occurrence. (More general case can be handled with some more involved twist.) Some technique used may be of some general interest. (I shortened some name to avoid potential wide-post.

's="?se=&da=&mo=4&Page=8&la=all&no=&Page=7&x=y&page=9&a=b"

.ignorecase=true
.pattern="page=.*?(\&|$)"

response.write s & "<br />" & t
