I didn't think long enough before answering that one ;-) I can see why one can't do that now that I've looked at code for a few minutes, and sorry for misleading anybody on this one. Ah, no, I think it's quite do-able, I just thought that you had an example at hand. The $filter argument is just a pointer to somewhere in the filter chain. So I suppose on could add a filter for the subrequest and pass $filter: $subr-output_filters. But as I don't have a test, I can't vouch for it to work. If you want I can write a test for it later, but now I need to resolve if a few other issues first. So let me know if you want me to work on this. -- __ Stas BekmanJAm_pH -- Just Another mod_perl Hacker http://stason.org/ mod_perl Guide --- http://perl.apache.org mailto:[EMAIL PROTECTED] http://use.perl.org http://apacheweek.com http://modperlbook.org http://apache.org http://ticketmaster.com -- Report problems: http://perl.apache.org/bugs/ Mail list info: http://perl.apache.org/maillist/modperl.html List etiquette: http://perl.apache.org/maillist/email-etiquette.html
write results of subrequest to file
I want to publish the result of a dynamic request to a file. So within a handler I create a subrequest that gives me the result of the dynamic request. Something like: $sub = $r-lookup_uri($page?id=$id); Now I want to get the results of this request and stream it into a file. Would using Apache::File be a possibillity? The main handler will continue and print if the write has been successfull.
