how would i go about retrieving (mod_perl or otherwise) the name of the immediate calling handler of the current handler being executed?
i'm trying to do loop checking in which a given handler may need to be executed as a result of multiple subrequests, but never back to back. e.g.: # httpd.conf ... # mod_transform uses an output filter to trap the content of a response # it lives at http://www.outoforder.cc/projects/apache/mod_transform/docs/ LoadModule transform_module modules/mod_transform.so # Apache::MyStuff cleans up uri->filename stuff <Location /foo> PerlTypeHandler Apache::MyStuff AddOutputFilter XSLT .xml </Location> so, the scenario here is that mod_transform needs to subrequest its external entities. these external entities need to be able to run once through the type handler, but only once, as the type handler will loop indefinitely. the timeline goes as such: * request comes in from a browser, or possibly a subrequest. * Apache::MyStuff examines uri. * Apache::MyStuff may run a lookup_uri here or there (these do not trigger Apache::MyStuff's handler because some sort of state is set). * http_core (or whatever) serves up a resource, probably xml. * if it's xml, mod_transform picks up and starts trying to dereference the external entities using its filter to trap the output. * as entities are being dereferenced, Apache::MyStuff is called once again as if the subrequest lookup generated by the entity dereference was an external request. so anyway, what i'm trying to figure out is how to set a state in a handler temporarily, so that subrequests spawned from it and it only do not cause it to recurse, but if it's invoked as a subrequest or internal redirect from another handler, it does its job. if anyone can suggest anything, i'd be greatly appreciative. thanks .d
