Is there another way to POST apart from response.redirect and XMLHTTP ?

**afrika** · Mar 15, 2005 13:28

hello
is there another way to post data to my provider's server apart from the response.redirect and XMLHTTP ?

I have tried both,
problem with response.redirect is taht the user coudl easily tell who my provider is, and XMLHTTP I cant get to read from the other server the request.querystring status

Any advice ?

Server.transfer??

**Thing** · Mar 15, 2005 21:43

Meta refresh.

**afrika** · Mar 16, 2005 03:04

meta refresh is a client side script

**afrika** · Mar 16, 2005 03:42

He never said it had to be server side. Just giving a different option.

**afrika** · Mar 16, 2005 06:51

Ok,

Am reading through the server.transfer and server.execute methods.

Seem to be a better alternative

**jimfraser** · Mar 16, 2005 08:23

I'm thinking you need to use xmlhttp - just explain better what you mean by querystring and I'll help you to get it working.

I'd guess that from this post and other posts you've made, you are doing the following:

- submitting a form (with known data) to a server (http://myserver.com/myurl?a=1)
- the "querystring" of that server is a=1. You already know that.
- that server is REDIRECTING to another URL (hence another "querystring")
- you receive the data from the server but you want part of the URL that was redirected to really.

If so, here is your code. I am using the MSXML2.ServerXMLHTTP object - you might need to upgrade your server to Microsoft XML 4.0 SP2 (download from Microsoft)

Code:

<%
sURL = "http://myserver/myurl?a=1"
sForm = "b=1&c=1"

Set oXH = Server.CreateObject("MSXML2.ServerXMLHTTP")


' If you are POSTING a form use this code:
oXH.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
oXH.open "POST", sURL, False

' If you are GETTING a page use this code:
oXH.open "GET", sURL, False


oXH.send sForm

If oXH.status <> 200 Then
	Response.Write "Status Error " & oXH.status
	Response.End
End If

sResult = oXH.responseText

sFinalURL = oXH.getOption(-1) ' -1 = SXH_OPTION_URL

Response.Write "The final page URL (after any redirects) is " & sFinalURL & "<br/>"
Response.Write "HTML of the page is <textarea>" & sResult & "</textarea>"
%>

I am hosting with my hosting provider, running win2k and IIS 5.0

Yes you are right.

Basically.
1. A user post his sms message to my website
2. MY site authenticates his credits and posts the data to my provider, which can be done via redirect or XMLHTTP
3. My provider's site posts the data and returns a code
- 100 means no credits on my account
-200 successful
-300 network cannot be found
-400 all carriers down

I am meant to be able to receive any of these posts and return to the user.

so far it works with the post, but reading the return variable is what i am having difficulty wiht. i normally get the error, access denied

I would try the above script and let you know

**afrika** · Mar 17, 2005 03:14

I get unspecified error
line 10

<%
sURL = "http://myserver/myurl?a=1"
sForm = "b=1&c=1"

Set oXH = Server.CreateObject("MSXML2.ServerXMLHTTP")

' If you are POSTING a form use this code:
LINE 10 >> oXH.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
oXH.open "POST", sURL, False

' If you are GETTING a page use this code:
oXH.open "GET", sURL, False

oXH.send sForm

If oXH.status <> 200 Then
Response.Write "Status Error " & oXH.status
Response.End
End If

sResult = oXH.responseText

sFinalURL = oXH.getOption(-1) ' -1 = SXH_OPTION_URL

Response.Write "The final page URL (after any redirects) is " & sFinalURL & "<br/>"
Response.Write "HTML of the page is <textarea>" & sResult & "</textarea>"
%>

**afrika** · Mar 17, 2005 03:15

If i take out line 10

i get parameter incorrect line 26

LINE 26 >> sFinalURL = oXH.getOption(-1)

**jimfraser** · Mar 17, 2005 05:17

My fault,

Cut from MSXML docs:

Note You must call the open method before you call setRequestHeader method. Otherwise, an error will occur.

so, switch line 10 and 11 =)

**afrika** · Mar 17, 2005 08:15

LINE 26 >> sFinalURL = oXH.getOption(-1) ' -1 = SXH_OPTION_URL

msxml3.dll error '80070057'

The parameter is incorrect.

/jim.asp, line 26

**afrika** · Mar 17, 2005 08:15

Hi Jim,
Am still getting an error on line 26

any assistance with this ?

thanks in advance

**jimfraser** · Mar 17, 2005 13:44

I checked the docs again, and regarding using getOption(-1) it says:

The URL, however, cannot be read until the open method is next called.

So, I'd try adding a (fake) open just before the getoption line, something like:

oXH.open "GET", sURL, False
sFinalURL = oXH.getOption(-1) ' -1 = SXH_OPTION_URL

Let me know if that works.

**afrika** · Mar 17, 2005 14:13

Same error
I was also doing some reading on the side about XML and its says it only works in IE 5 and above, so i wonder what would happen to other browsers

Same error below

LINE 26 >> oXH.open "GET", sURL, False
LINE 27 >> sFinalURL = oXH.getOption(-1) ' -1 = SXH_OPTION_URL

**afrika** · Mar 17, 2005 14:13

sorry

msxml3.dll error '80070057'

The parameter is incorrect.

/jim.asp, line 27

**jimfraser** · Mar 17, 2005 21:27

You shouldn't be getting msxml3 errors with
MSXML2.ServerXMLHTTP
are you using the right component?

**jimfraser** · Mar 17, 2005 21:54

OK I got it working - kind of. It was creating an MSXML3 object. This example works, try it with your target URL.

Code:

<%
sURL = "http://www.latlink.net"

Set oXH = Server.CreateObject("MSXML2.ServerXMLHTTP.4.0")

oXH.open "GET", sURL, False
oXH.send

If oXH.status <> 200 Then
	Response.Write "Status Error " & oXH.status
	Response.End
End If

sResult = oXH.responseText
sFinalURL = oXH.getOption(-1)

Response.Write "The final page URL (after any redirects) is " & sFinalURL & "<br/>"
Response.Write "HTML of the page is <textarea>" & sResult & "</textarea>"
%>

**afrika** · Mar 18, 2005 02:30

**afrika** · Mar 18, 2005 02:43

However Jim, if i may ask, what documentation are u using?

I do understand that XMLHTTP, dont work with other browsers except IE 5.0 ?

Is this correct esp for the 3.0 object of XML

**afrika** · Mar 18, 2005 02:54

I just tested it on Opera, and it works well. so i guess its really ok then

**jimfraser** · Mar 18, 2005 05:20

Afrika,

Since we're using it as a server side component, the browser doesn't matter.

It's possible to use xmlhttp in browsers through javascript (similar to what Google Suggest does) but we're not doing that =)

**afrika** · Mar 18, 2005 05:32

Ok,
I was wondering, cos one documentation i read said it was compatible with certain browsers.

Also i was wondering why, the response.redirect could be read by a client. I also thought it was a server side component, until i started to use it to send secret info and saw its visible to all.

I really am not good with jscript. I stick only to VB, although we have 2wizards inhouse with jscript. For server side i stick to vb script

**jimfraser** · Mar 18, 2005 05:41

The documentation for MSXML can be installed when you install the component by the way - it's not selected by default though.
