# Include Topics and Web Pages Using **%INCLUDE\{...\}%**
Variable
Use the **%INCLUDE\{...\}%**
variable to embed the content of another topic or web page inside a %WIKITOOLNAME% topic. The whole content or only parts of a page can be included. If needed, set a proxy server in [[TWikiPreferences]].
**%INCLUDE\{ "page" pattern="reg-exp" rev="1.2" \}%**
- **"page"**
: %BR% The nameless parameter specifies the page to include. It is
- The name of a topic located in the current web, e.g., **%INCLUDE\{"WebNotify"\}%**
- A `Web.Topic` name specifying a topic in another web, e.g., **%INCLUDE\{"TWiki.SiteMap"\}%**
- A full qualified URL with **http**
protocol, domain name and optional port number, e.g., **%INCLUDE\{"http://twiki.org:80/index.html"\}%**
. Supported content types are **text/html**
and **text/plain**
. The full page is included by default, but the HTML header and scripts are stripped in case it is a web page.
- **pattern="reg-exp"**
: %BR% The **pattern** parameter is optional and allows you to extract some parts of a web page. Specify a [[RegularExpression]] that scans from start (`'^'`) to end and contains the text you want to keep in parenthesis, e.g., **pattern="^.\*?(from here.\*?to here).\*"**
. You need to make sure that the integrity of a web page is not compromised; for example, if you include a table, make sure to include everything including the table end tag.
- **rev="1.x"**
: %BR% The **rev** parameter is optional and allows you to include an earlier revision of a topic. This can be used to include an official version of a topic, e.g. one that has been signed of by management. This parameter does not apply to URLs.
**_Note:_** All text of a topic is included unless you specify **%STARTINCLUDE%**
, **%STOPINCLUDE%**
and/or a **pattern** parameter. A pattern will only search between **%STARTINCLUDE%**
and **%STOPINCLUDE%**
.
