ASPTear Component

Component Properties

The following table describes which properties are supported by the AspTear component. Property names are in Italic. Get means that the property value can be read, set means that it can be changed. Default values are also described.

 

Property	Description
Accept get/set - default: "text/*"	Defines the HTTP_ACCEPT header. By default, only text documents are handled by this component. (*)
ConnectionTimeout get/set - default: 2000	You can set a connection timeout for connecting to remote web servers. This property is defined in milliseconds.
ContentType get/set - default: "application/x-www-form-urlencoded"	Best to leave to the default - this default content type is needed to successfully GET and POST to ASP pages.
FollowRedirects get/set - default: True	Specify whether the component should automatically follow redirects (302's)
ForceReload get/set - default: False	Use to prevent local caching from WinInet (component will always roundtrip to server)
Headers get only - returns headers after retrieve operation	Retrieve the headers after the retrieval of the document.
HttpVersion get/set - default: "HTTP/1.0"	Determine the version of HTTP that should be used to connect to the remote Web server.
IgnoreInvalidCertDate get/set - default: False	Allows you to ignore invalid certificate expiration dates - for example, certificates that have already expired would cause the page not to download.
IgnoreInvalidCN get/set - default: False	Allows you to ignore invalid common names in certificates. For example, the certificate was issued for www.domain1.com, but is used for www.domain2.com - then the CN is invalid.
Port get/set - default: not set, autodetermine	Set port number manually. Preferred way is by appending to URL, like http://www.alphasierrapapa.com:8181
Proxy get/set - default: "" (no proxy)	Enter the proxy server you want to use for accessing the Internet. The full URL including protocol and port must be supplied, eg: http://proxy.alphasierrapapa.com:8081
ProxyUsername get/set - default: "" (no username)	Use for proxies that require authentication other than Windows integrated (MS Proxy or ISA).
ProxyPassword get/set - default: "" (no password)	Use for proxies that require authentication other than Windows integrated (MS Proxy or ISA).
RedirectTarget get	When using FollowRedirects=False, you can determine the redirect target using this property.
Referrer get/set - default: none	You can set the referrer if the page you are calling needs one.
SendClientCertificate get/set - default: False	Set to True when you want to send a client certificate when connecting to an SSL secured Web site. Please see the section entitled Client Certificates for more information.
TrustUnknownCA get/set - default: False	If you don't have control over the machine where IIS is running on, the IIS certificate authority store cannot be updated using the iisca utility. In that case, you can tell the component to simply trust any CA it comes across. (**)
UserAgent get/set Default: "Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0; AspTear 1.5)"	If you need to set a specific user agent (eg, you want to retrieve a page that does a browser check and acts accordingly), simply change the personality of the component.

(*) In the current release, you can set only one Accept type. If you want to receive any content, simply use "*/*" as Accept type.

(**) The iisca utility can be found in the WINNT\system32\inetsrv directory. It allows you to copy root certificates from the user's root store to IIS's root store. This must be done for every new CA you want to trust.
