Apache::ProxyStuff is module for adding headers and footers to content proxied from other web servers. Rather than sandwiching the content between the header and footer it "stuffs" the header and footer into their correct places in the content -- header after the <BODY> tag and footer before the </BODY> tag. This allows you to give content living on established servers a common look and feel without making changes to the pages. (ProxyStuff will add <BODY> and </BODY> tags appropriately when the document does not contain them. This allows even syntacticly incorrect pages to have a common header and footer.)
ProxyStuff also allows you to add meta tags to the <HEAD> section, attributes to the <BODY> tag and manipulate links, image refs and form actions as needed.
HeaderFile specifies the URL of an HTML page that will be used as the header for proxied content. It will be added after the first <BODY> tag.
Example: PerlSetVar HeaderFile http://www.bar.com/includes/header.html
FooterFile specifies the URL of an HTML page that will be used as the footer for proxied content. It will be added before the </BODY> tag.
Example: PerlSetVar FooterFile http://www.bar.com/includes/footer.html
ProxyPrefix specifies a URL which will be prepended to the URI of the request. The new URL is the location of the content to be proxied. If /proxy/content.html is requested and ProxyPrefix is set to http://www.foo.com, the content will be proxied from http://www.foo.com/proxy/content.html.
Example: PerlSetVar ProxyPrefix http://www.foo.com
MetaDescription allows you to add a description meta tag to the <HEAD> section of the requested document.
Example: PerlSetVar MetaDescription "ProxyStuff Home Page"
MetaContent allows you to add a content meta tag to the <HEAD> section of the requested document.
Example: PerlSetVar MetaContent "Apache, mod_perl, proxying"
BodyAttributes allows you to add or modify attributes in the <BODY> tag in the proxied content. If you specify an attribute that exists in the <BODY> tag of the proxied page, the attribute that was in the page will be overwritten with the one you specified. If your attribute does not exist in the original <BODY> tag it will simply be added to the tag.
Example: PerlSetVar BodyAttributes 'BGCOLOR="#FFFFFF" VLINK="BLUE"'
If StripHost is turned on, ProxyStuff will assume that the hostname of the server providing the content is the first part of the URI. For example, if the URI of the request is /foo/some/content.html and ProxyPrefix is set to http://www.foo.com then /foo will be stripped from the URI and a proxy request will be made to http://www.foo.com/some/content.html.
(This is useful if your site is divided up into unique sections with their own headers/footers and each section has content proxied from multiple servers -- /foo/hr, /bar/hr and /baz/hr.)
Example: PerlSetVar StripHost Yes
AddHost2AHref, AddHost2ImgSrc and AddHost2FormAction are often used in conjunction with StripHost when your proxied content contains absolute links. ProxyStuff will add the provided text to the beginning of HREFs, SRCs and ACTIONs so these URLs are correctly mapped to ProxyStuff directories.
For example, you set up <Location /foo> to use ProxyStuff. ProxyPrefix is set to http://www.foo.com, StripHost is turned on and AddHost2AHref, AddHost2ImgSrc and AddHost2FormAction are all set to foo. A user requests /foo/some/content.html. ProxyStuff removes /foo and requests http://www.foo.com/some/content.html. The page returned contains links such as <A HREF="/some/content.html">Link</A>. ProxyStuff will turn the link into <A HREF="/foo/some/content.html">Link</A> so when a user clicks on the link, the request will be handled by Apache::ProxyStuff.
Example: PerlSetVar AddHost2Href foo
Apache::ProxyStuff requires mod_perl, LWP and HTML::TokeParser.
