URL rewriting with ASP

I need to rewrite a URL like:

FROM: /mypage.asp?my_id=78

TO: /contact-us

Where contact us is the name of that page stored ion a database.

I can easily use a ISAPI filter to change it to:

/page/78/contact-us

HOWEVER i do not want the "78" in the URL. The reason for this is that
site is already established under names like "/contact-us" as it was
done is .net somehow.

Anyway of doing this in ASP?

I had the idea of physically creating the folder "/contact-us" using
the FSO and thendropping in an index file which searched the database
for the ID based on the name of the page, then set a session based on
that ID and then did a server.transfer to the "mypage.asp" and changed
that page to look for the session rather than the querystring.

Just wondering if anyone has a neater way?

Regards and thanks for your time.

Dave.

Dave,

I'm finding it a little bit confusing to follow what effect you are really
after. It seems to be an unusual direction, normally one takes a
non-existant url such as /contact-us and re-writes it to a specific one like
/mypage.asp?my_id=78 for actual processing. What you seem to be asking for
is the other way round, is that correct?

You indicate that currently /contact-us doesn't physically exist. What do
you expect to happen when you attempt to re-write the URL to /custom-us?

If you need to pass on info to whatever processes the /custom-us URL such as
the user ID you can have your ISAPI filter add a custom header to the
request.

Re: URL rewriting with ASP

yes, "/contact-us" does not exist and I wish oit to re-write to the "/
mypage.asp?id=78"

The only way I have it done is using a ISAPI filter but that requires
that the id "78" or whatever is in the URL to be re-written

eg: "/78/contact-us"

HOWEVER i do not wish to have the "78" there - the reason for this is
that the website is already established and therefore the SEO links
are already looking at "/contact-us" - I want to keep this
functionality so as to not affect the SEO rankings. PLUS the client
wishes keep it this way.

The only way I have found is using custom 404 errors to extract the
"contact-us", look in the database for this title in order to find the
id of the page, then set a session equal to the ID then
server.transfer to the "mypage.asp"

This make sense?

Re: URL rewriting with ASP

you can do it overwriting 404 http error

It's getting closer but still a little muddy.

I take it that if the "78" in all this is some kind of user ID or some other
data which may vary.

In that case if you want the existing URL to remain simpy "/contact-us" then
where would the ID value be held? A cookie? Session variable? or something
else?

EXACLTY, that is the question I am asking. I assume a session
variable.

The 78 refers to the Id of the page held in the database.

I see lots of websites with /contact-us which are obviously database
driven - just wondering the best way to do this in ASP

see bbrail.com for example

If the id is in a session variable, what is it doing in the url?

Ok still trying to demystify your requirement. I think your in a situation
where depending on the context of the current user session a visit to
/contact-us is expected to generate different results. An ID is to be
associated with the users session that specifies that content. I doubt I
have that right but in case I do:-

Store the ID in the Session object, use the 404 kludge, test that
/content-us is being requested, server.transfer to mypage.asp and have
mypage.asp retrieve the value its interested in from the session object.

Alternatively get the ISAPI filter to re-write the url to mypage.asp which
can still retrieve the ID from the session object.

Thanks for your reply

===============================

This is exactly what I thought I would need to do.

I was wondering whether there was any other way - I know about the
ISAPI filter method but that would require the ID being in the URL
somewhere.I DO NOT want this to happen.

One way I figured was:

1) "/contact-us"
2) ISAPI rewrites this to "mypage.asp" passing "contact-us" as a
querystring
3) "mypage.asp" looks in database for "contact-us" and then displayed
the relevant page content
4) alternatively on the "mypage.asp" if the querystring returns
"*.asp" then server.transfer to that ASP page. (cos not all of the
websites pages are dynamic database driven)

Does this make sense as to what I am tring to do?

Unless I can use the ISAPI filter to only kick in when ".asp" is NOT
found in the URL of course.

Apologies if I am/was not making sense - its quite hard to explain
what I am trying to acheive.

What I think you want keeps changing. It isn't helping that your not
responding to statements I'm making that don't match what you want.

Now what I think you want is that there will be a number of different URLs
referenced in the system which don't actually exist and you want to trap
those in order to send the appropriate output. Again I still don't think
I've got it. But in case I have:-

It sounds like what you are looking for is the 404 trick. However instead
of the 404 custom handling page transfering to mypage.asp, the 404 custom
handler _IS_ mypage.asp. Now all the mypage.asp has to do is use the URL
(already provided in the querystring by IIS on encountering a 404) as a key
to lookup the content to be sent. This ditched the numeric ID altogether.

I would avoid writing an ISAPI filter unless it's absolutely necessary.

Are we getting there?

Re: URL rewriting with ASP

Hi Dave,

To hide the location.href values of documents that you present to the user,
you need to use frames for site navigation and not open documents in their
own window/tab.
Here are some snippets from my site

In my root folder, the start page is set to Index.asp, which can accepte an
optional parameter 'url'
<%@ Language="VBSCRIPT" %>
<%
dim sURL
sURL = Request.QueryString("URL")
if len(sURL)=0 then
sURL = "Welcome.asp"
end if
Session("CurrentPage")="Welcome.asp"


%>
----------------------------------------------
My Index page is a frames page with two frames




In each page I put the following script



This will test to see if the page has a parent (frame) as it is being
loaded. If it doesn't it will change the document.location.href value to
reload the page via the index page eg. http://mydomain.com/apage.asp becomes
http://mydomain.com/?url=apage.asp, reloading the page in a containing
frame.

To the user, the address displayed in the Address bar never changes, the
current document Title is displayed in IE's title bar.

Each page has the context menu disabled to stop users using the 'Add to
Favorites' and 'Properties' options to reveal the true url.

I place a Add to Favorites and and Email a Friend button on each page to
replace the built in IE functions



///////////////

The covenets of this is that users can defeat it if they have scripting
disabled in their browser settings so it is important to use
