0 = ascii / text
1 = binary
Defaults is:
0 ascii mode

Notes: You must set "binarysaveas" using a full path and file name.

example inet.binarysaveas = "c:\binaryfiles\image.gif"

Set this to 1 to ignore the following SSL certificate errors:

INVALID CA - means the certificate was created by a CA not known to your machine.
HTTP TO HTTPS ON REDIRECT - prevents errors when being redirected from HTTP to HTTPS sites.
HTTPS HTTP SUBMIT REDIRECT - prevents errors when posting to non SSL sites from SSL sites.
HTTPS TO HTTP ON REDIRECT - prevents errors when being redirected from SSL to non SSL sites.
CERTIFICATE COMMON NAME INVALID - prevents errors when the CN does not match the certificate. This occurs when you're trying to use www.site.com's certificate on testserver.site.com.
CERTIFICATE DATE INVALID - self explanatory.
CERTIFICATE REVOKED - self explanatory.
CERTIFICATE INVALID - self explanatory.

example:

Dim inet
Set inet = CreateObject("khttp.inet")
dim url
url = "https://your_secure_domain/yourpage"
inet.ignore_ssl_errors =  1
response.write inet.openurl(url)
Set inet = nothing

inet.bypassUrlEncodeOnPost = 0 DEFAULT
This will enable automatic urlencoding of post variables.

inet.bypassUrlEncodeOnPost = 1
This will disable automatic urlencoding of post variables.

example:

Dim inet
Set inet = CreateObject("khttp.inet")
dim url
url = "http://yourdomain/yourpage"
response.write inet.openurl(url)
response.write inet.openurl(url,"GET")
response.write inet.openurl(url,"POST")

dim your_protected_url
your_protected_url = "http://yourdomain/yourprotectedpage"
inet.username = "your_username"
inet.password = "your_password"
response.write inet.openurl(your_protected_url)
response.write inet.content
response.write inet.contentlength
response.write inet.headers
Set inet = nothing

example:

Dim inet
Set inet = CreateObject("khttp.inet")
response.write inet.urlencode("123+456 789")
Set inet = nothing

example:

Dim inet
Set inet = CreateObject("khttp.inet")
dim url
url = "http://yourdomain/yourpage"
inet.addpostvars "test1","one"
inet.addpostvars "test2","two"
inet.openurl url,"POST"
response.write inet.content
inet.clearpostvars
inet.addpostvars "test3","three"
inet.openurl url,"POST"
response.write inet.content
inet.clearpostvars
Set inet = nothing

example:

Dim inet
Set inet = CreateObject("khttp.inet")
url = "http://www.rainfall.com/variables.asp"
inet.addHTTPHeaders "referer","http://www.rainfall.com/"
inet.addHTTPHeaders "User-Agent","khttp activex component"
inet.openurl url
display inet.content
inet.clearHTTPHeaders
Set inet = nothing

Dim inet
Set inet = CreateObject("khttp.inet")
url = "http://www.rainfall.com/mainimages/rf1_01_01.gif"
inet.transfermode = 1
inet.binarysaveas = server.mappath("rf1.gif")
inet.openurl url
display inet.content ' display a success/failure message
Set inet = nothing

dim inet
dim xmlDocument ' you must supply a valid XML document
dim url

Set inet = CreateObject("khttp.inet")
url = "https://www.ups.com/ups.app/xml/Rate"
inet.xml = xmlDocument
inet.openurl url,"POST"
display inet.content
Set inet = nothing

Fixes a bug where certain downloaded binary files would be corrupted..

v1.4.3 - 11/04/2002

Solves some issues where khttp might not return control if a site was not responding in a timely fashion.

v1.4.2

Added additional property 'bypassUrlEncodeOnPost'. This addresses issues with some non-conforming http sites that do not properly parse urlencoded values.

Initially, khttp encoded all variables using the post method, so while most servers interpreted '%41' as 'A', some home brew CGI did not. We've now included an optional switch - see properties.

v1.4.1
Added ability to add custom cookies to http header and manual http redirection. This update may cause changes in your current khttp implementation if you previously had relied on autoredirection. Cookies are now handled entirely via http headers. refer to Netscape Cookie Reference for cookie header details if you wish to use cookies.

v1.4.0
added support for non-standard SSL certificates. This means khttp will now ignore SSL errors like invalid name, out of date, etc. Refer to the docs for usage.
