Request.Servervariables redirect

I want to give each item in my Db it's own "static" page. I will do that by capturing the id and passing the id number to a search page.  I want to see if it is possible to pull the item number directly from the url without having to include a .asp file in the url.  

Example:

www.somerandomsite.com/123456  which i would pull the number 123456. and redirect to the search page.

i can do this with www.somerandomsite.com/default.asp?123456 but am trying to keep the url as short as possible and allow any user to be able to remember what to enter without having to type in all that information.

Is there a way i can force all request for that directory to go to the default.asp page and then pull the last digits off, again without making the user type in default.asp.


Thanks in advance

You can write an ISAPI filter for this.

(OnUrlMap)

find out the number and redirect it to the related page.

How complicated is that.  I haven't done it before.

very :)

just write a default.asp that takes a querysting parameter say called page id then in the default.asp take the id get the page and then do a response.redirect. you could even store the page in the db and just print it to the user..

i.e

default.asp

pageid = Request("pageid")
Set con = Server.createobject("ADODB.Connection")
con.Open your dsn
Set rs = con.Execute("SELECT * FROM pages WHERE page_id = "pageid)

THEN EITHER

response.redirect(rs("filename"))

OR

response.write(rs("contents"))

filename will be the name of the file and it will be held in the db or you could hold the whole contents and use response.write to put it out.
the contensts will have to be a memeo field

this will work but i cant advertise every item as www.somerandomsite.com/default.asp?id=12345.

it just isn't memorable and the average consumer wont remember it.  which is why i'll have to check out isapi unless someone has another suggestion.

thanks

even if you use an isapi you will still have to pass it some kind of identifier so it can detaermine the page to display...

writting an isapi will be a serious over kill here

Maybe this helps. But youwill have to do a bit of digging. In Apache there is an option called MultiViews or the Alias option.

For example if you have MultiViews turned on and you have a file called
abc.cgi in your document root, (or if /abc is Aliased to abc.cgi)
then requesting:
    http://my.domain.com/abc/foo
.... would run abc.cgi with the PATH_INFO server-variable set to 'foo'.

So if you query for SERVERVARIABLES "PATH_INFO" u will get 'foo'.

Check out if your web server supports aliases and then u should be able to do what u want.

You can set up custom error responses.
For instance, if you request :

http://www.somesite/dir/page.asp and the page is not there you get a 404 error and an error page is displayed.

You could configure your server to display http://www.somesite/dir/default.asp whenever a 404 ocurrs in that directory.

Then you use default .asp to query the headers and display the real page either by redirecting or by pulling it into a full-size frame within default.asp.
