I don't know, but both urls works with Multiheadlines.
I tested myself.

I think it's because in the 'Add Feed URL' inside Feed URL Management section:

Adding long RSS URL is accepted but once you save it, the end of link is cut off.

For example:

"http://www.mysite.com/modules.php?op=modload&name=MyHeadlines&file=index&myh_op=section&myh=backend&myh_sect=2"

Thats a pretty long RSS URL, now when I save it, it becomes:

"http://www.mysite.com/modules.php?op=modload&name=MyHeadlines&file=index&myh_op=section&myh=backen"

You see, URL is cut off at the end.

I'm not sure where I can change the limit of URL length.

Please advise.

Ah, I just figured it out myself. I had never done this before.

What I did was go into phpmyadmin and then check structure of the urls_url field and change from varchar(100) to varchar(150)

That solved the problem!

Hmmm indeed this is a good point[long urls] although I didn't encountered yet urls longer than 100 chars. Maybe I'm gonna increase the length to that field[from db].

Yeah, rare instances where urls are that long.

I use MyHeadlines because its had many years to mature and it strips out html tags efficiently. It has subscription base where members can subscribe to specific RSS feeds. Also features scraping technology where we can program some bots to extract headlines off sites that does not have feed urls.

I have used it for a couple years and am familiar with it. Not that I dont like your script, it's pretty good for its age. I will use it for news based sources while I use MyHeadlines for blog sources only.
