Howard M. Lewis Ship resolved TAPESTRY-786:
-------------------------------------------
Resolution: Invalid
Assign To: Howard M. Lewis Ship
This is what the request decodere extension point is for; it can provide the
real server name and port to use, when the values returned by the Servlet API
are incorrect, due to the presense of a firewall.
> wrong rendering of links when changing scheme binding
> -----------------------------------------------------

> Key: TAPESTRY-786
> URL: http://issues.apache.org/jira/browse/TAPESTRY-786
> Project: Tapestry
> Type: Bug
> Components: Framework
> Environment: Tapestry 4b13, Tomcat, Apache
> Reporter: Gerald Schoeffel
> Assignee: Howard M. Lewis Ship
>
> When a page is rendered after changing the scheme binding, every link on that
> page contains 'wrong' portnumbers.
> Example:
> My local server (Tomcat) ist running on port 8080, https is listening on
> port 8443.
> In the border-component there is the following definition:
> <component id="loginpage" type="PageLink">
> <binding name="page" value="'Login'"/>
> <binding name="scheme" value="'https'"/>
> </component>
> The generated link looks like https://localhost:8080/... .
> When using a proxy server (Apache 2.x) to get requests to port 80 forwarded
> to my container, having https on port 443, the generated link is
> https://mydomain:80/.... :(
> When fixing the port-part of the link and entering this in the browser, the
> page is rendered with all inks on it containing https :(
> Links having scheme bound to 'http' are rendered with the wrong port-number
> (now the https-port). So there is no way back :(
> With the help of Kent Tong (tapestry mailing list) I could implement a
> workaround:
> protected String constructURL(ILinkComponent component, IRequestCycle
> cycle) {
> ILink link = component.getLink(cycle) ;
> String scheme = component.getScheme() ;
> String anchor = component.getAnchor() ;
> WebRequest request = cycle.getInfrastructure().getRequest() ;
> int httpsPort = request.getServerPort() == 80 ? 443 : 8443 ;
> int httpPort = ((request.getServerPort() == 8443) ||
> (request.getServerName().equalsIgnoreCase("localhost"))) ? 8080 : 80 ;
> if ((null != scheme) && scheme.equalsIgnoreCase("https"))
> return link.getURL(scheme, null, httpsPort, anchor, true) ;
> return link.getURL("http", null, httpPort, anchor, true) ;
> }
> }
> Binding this LinkRenderer as the render in PageLink etc. components will work
> - but static links, hardcoded on the page will be rendered wrong.
> Would be great to get this fixed and/or improved to enter and leave different
> schemes easier.
> Thank you in advance !
