I always wanted to give users (well, myself!) a way to subscribe a Topic, Forum, Category, or All of the above RSS Feed, kinda like, if you are in a topic, you can subscribe the Feed for that topic, that topic's Forum, that category's Forum, and all of it.

So, this dawn I just did it and give to Marcel (www.oxle.com) as well because as I said before, I wanted this to my own

the code of the <b>rssFeed.asp</b> file can be found here

and this is the code header:

you can always just use it in the normal RSS Feed way, just, this gives you much more options.

fell free to criticize

It's a very strange coincidence: the logs of the sites show that the last successful accesses to the sites had been done just a few minutes before I updated the forum.

Anyway, I have now restarted the server (the good old method of turning off/on which is so common in Windows o.s....) and it seems that everything is working correctly. Probably some setting or data had been cached somewhere.

Thank you

there are no RSS server level parameters that I am aware of, RSS is simply a request protocol for delivering news feeds, the file is simply a file that gets data from the database and creates an xml rssfeed rather than a webpage, I don't see how it can have had anything to do with the problems you have described, it is most likely a complete coincidence.

simply having the rssfeed file in your forum can not possibly cause any problems, it has to be accessed for it to even run any code, it can't do it on it's own.

After installing this RSS mod, all my Joomla sites containing RSS feeds stopped working. They just displayed a message like this:

Fatal error: Maximum execution time of 30 seconds exceeded in D:\inetpub\vhosts\vrconsulting.it\httpdocs\libraries\simplepie\simplepie.php on line 7693

The same issue was not only on the domain where the forum is located, but also on two other sites, belonging to different domains, which have nothing to do with this forum, but just happen to be hosted on the same server!

I restored the old forum configuration (removing rssfeed.asp and reloading the original inc_header.asp ) but the problem was still there.

I reinstalled these sites from yesterday's backup in order to get them working again. But even the full restore was not enough: I had to remove completely any RSS feed from all the domains hosted on my server.

That mod has changed some general server configuration, without giving any warning !

I am usually very careful in updating software on my server, but all the mods I installed in my forum have always affected only the forum itself, and nothing else.

Can anybody please tell me what RSS parameters at server level does this mod change, and where they are, so that I can try to restore a working situation, without having to perform a full restore of the whole server ?

Thank you

new version with the ability to hide replies from Feed, in other words, just show Topics.
AnonJr Posted - 07 December 2008 : 19:49:33
I'll have to look and see which one it was. It may be up on Snitzbitz.com and wasn't posted here.

There are more than just those two floating around. Some have been archived, some use different terminology (Atom feed, rss feed, etc.). I'll have a lot more time this week so I may spend a little time making the improvements to the one I have and release it back.<
balexandre Posted - 07 December 2008 : 09:39:24
is it me or there is no such code on this forum AnonJr?

I searched for rss mod but I just found mini MOD and Marcel RSS Feed

can you provide me the link for that please <
AnonJr Posted - 06 December 2008 : 23:42:01
There's another RSS MOD floating around out there that does pass a partial hash of the password. Might be worth looking into.<
balexandre Posted - 06 December 2008 : 16:57:04
Updated to v.1.1

With this version there are Good News and Bad News...

the bads
  • I almost killed myself looking for a free way to Encode/Decode strings in Classic ASP (with a user password) but I found nothing! (ASP.NET has this in the framwork, so it will be esier to implement such feature in the ASP.NET version of Snitz
  • For this I do not use UserID on the parameter


the goods
  • I still encode the feed type and the feed ID (Cat_ID, Forum_ID, Topic_ID)
  • I do not show messages in the RSS that the forum is not public (as you can see in the live example)
  • The MOD is free to everyone

SiSL Posted - 05 December 2008 : 18:59:58
I think sounds nice :)

I'd say: go for it :)<
balexandre Posted - 05 December 2008 : 14:42:05
Cookies are never a good idea...

Imagine that the user opens the Google reader only in an online caffe. He will never see new topics/messages/replies because the lack of the cookie

if the RSS Feed is something like

http://www.mydomain.com/rssFedd.asp?url=wtey7866twWTY812Byh3xxwe

then what can the User do?

he is subscribing to that URL, and that contains Topic, Category, Forum and even UserID so the rssFeed script can hide from him all the foruns, replies, etc that he can not access from Snitz Forum

how about that?

I did inplemented this approach in a client website to send the correct officeID and date gap in order to see a PDF report or see the report online, for my prespective, it's the safer route.<
SiSL Posted - 05 December 2008 : 14:12:47
Well, may be you may place a forum cookie check before XML Response, so if user did not checked "Save password", they may not reach the topics... If they do and have access they could... ;)

Based on QueryStrings, some problematic users can always think they hacked(!) it and see (for example Moderator boards a topic called: Should we ban 'SiSL'?") ofcourse as you said, there is always chance to shut them down manually but hey, in the end, why not perfectise it while you are at it :)
<
balexandre Posted - 05 December 2008 : 11:48:04
I just remember ... I can always encode the QueryString and pass the user ID as well, and this will prevent any other user that does not have access to the message to retrieve it, and any other bad user to hack the encoded URL, unless one knows the encoding password.

Does this help(of course it will help, but, is this ok for you SiSL)?
to everyone else, should I do this?<

A straight answer: Yes!

But one can only Subscribe a topic that one can see, unless they hack it (changing the Cat_ID, Forum_ID or Topic_ID, but for that you can prevent them to read the message content:
vgShowFullPost	= false
vgShowMaxChars	= 0


that will only give the topic name and that is all, soon they click "read more" link from there Rss Reader, the Forum will ask them to login and give an error for that topic to be read

is this ok?<
Shaggy Posted - 05 December 2008 : 10:27:16
Haven't added the script but I cursory glance would suggest that they can.
