Forum OpenACS Development: Re: rp_handler and host-node mapped subsites

Ryan, Eduardo,

I agree, openacs-core things break in host-node mapped sites. Many times, it's because a package is limited to a single mount, often outside of the host node mapped file hierarchy. These should be re-worked to handle more general cases.

I guess what I'm saying is that the rp_handler is not the place to be throwing form posts. Use it to generate urls that work in the first place.

Most apps reside within a single directory. By omitting all forward slashes, browsers use existing directories. The case is simple for all these host node map directories.. no change required. For example, take a look at birdswelcome.com All the forms in that site use post. All are in a single directory. No issues, even when accessing via dekkasupply.com/birdswelcome

For apps that require processing between a hostnode-mapped domain and the main-domain, such as login and register, build the post and return_url ahead of time using absolute references.

site_node::conn_url is helpful. It is especially useful in a place like index.vuh in a hostnode-mapped directory.

Here's an example from universallogos.com/index.vuh

set conn_url [site_node::conn_url]
set conn_url0 [ad_conn url]
ns_log Notice "/www/universallogos/index.vuh conn_url = '${conn_url}', ad_conn url = ${conn_url0}"
if { $conn_url eq "" } {
    regsub -- {/universallogos/} $conn_url0 {/} conn_url
}

if { [string match "/resources/*" $conn_url ] } {
    set redirect_url "/www${conn_url}"
    rp_internal_redirect $redirect_url
    ad_script_abort
} elseif { [string match "/search/*" $conn_url ] } {
    set query [ns_conn query]
    set redirect_url "http://dekkasupply.com${conn_url}?${query}"
  ns_log Notice "/usr/local/www/dekkasupply.com.com/openacs-4/www/universallogos/index.vuh: redirecting to: ${redirect_url}"
    ad_returnredirect -allow_complete_url $redirect_url
    ad_script_abort

} else {

    ::xowiki::Package initialize -ad_doc { 
 
        The script uses an XoWiki page as root page 
        of the site. Here, the start page is /xowiki/ followed 
        by the actual URL, as specified as the value after "-url" below. 
        Replace this value, in case a different XoWiki instance 
        name should be used.

Perhaps you missed the second point in that post.

It begins with: "For apps that require processing between a hostnode-mapped domain and the main-domain"..

Also, see my previous post to Eduardo regarding building return_url in ad_get_login_url.

You should be able to build a proc that returns the absolute reference you need, without messing with the request processor or redirecting.

Are you trying to hide a form processing url from the web? If so, put the form processing in an index.vuh page. No redirect required.
