sure i'm interested cultiv8r!
but i dont know cf or delphi, but i heard that
delphi is the same as pascal (which i learned 5 years ago
when i was 10).

by the way,
i have submitted tshdos' hostcache to gnucleus and
its now working....

Yup. A fairly extended version of OOP Pascal, but still the basic syntax. Still able to run Turbo Pascal 3.1 apps without many changes, but who would want that these days *g*.

Cool, saw it running. Looks good, fast response too. One thing I'm so eager about GWebCache is that I advocated a similar system not too long ago. There are plenty of user who have a website or home-based webserver that don't mind providing the service of a host cache - but a pure Gnutella-based host cache is a bit overkill for all what it is supposed to do. Hope it catches on well!

Do you mean a host cache which is not only caching but connecting directly to other nodes like I said as a pure Gnutella based host cache? I think this would be better because the GWebcache method works only indirectly (you have to report Gnucleus) and although Gnucleus is great - I really hate it to be addicted to anybody. The other method works without Gnucleus too.

I was more referring to a full-fledged Gnutella client, such as gnutellahosts.com using BearShare for the purpose handing out a few pongs. If you'd like host caches widely spread among more comon users (think in terms of people using websites hosted at an internet provider or at home), such will not succeed. You'll need to have a system that takes up less resources, etc. You can still connect to other host caches, and exchange data, but it shouldn't be as frequent as what we're accustomed to with a true Gnutella client. Another issue, again focusing on the common users, is that Web services are usually limited to HTTP or FTP. If one can fully utilize that, which is something the current GWebCache comes close to, then that's of course excellent. But, it's all a matter of opinion though - I tend to use examples that hit closer to home.

I like the idea of an ISAPI extension and was actually starting to write one in C++ after I finished the ASP one.
I was also considering writing a small web server app that would function like the GWebCache but would not be reliant on any web server software.

No problem, I am not trying to compete with anyone. I would just like to see more options all around.

cultiv8r, does the cfcontent tag really remove all the extra whitespace? When I used to use cold fusion, that was one thing that really annoyed me. I think when CF5 came out they finally added an option to eliminate the whitespace but I switched to ASP before I ever had a chance to try it.

The problem of leading spaces still exists in CF5, but using the CFCONTENT you can indeed fix that problem now. Just use it like this:

<CFCONTENT type="text/html" reset="YES">

That's why CF version GWebCache needs that tag enabled, otherwise clients that do not expect a leading space will assume there was an error. If the tag is disabled for security issues, there are some other workarounds for that problem but are not elegant. Wish Allaire/Macromedia put in some efforts in fixing that issue, it's been around for quite a while now. Haven't had the chance to try CF MX yet...

hey tshdos,
here is my own written hostcache:

I just looked at your newest version (0.3). Looks good but I have a couple of suggestions for you.


Line 23:
If Request.Querystring("restart") = 1 Then StartASPEngine '//Change The Default Value


You should probably remove this or add a check for security.


Line 40-47:
If Request.Querystring("url") <> "" Then
UpdateHostCache
Status = "OK"
End If
If Request.Querystring("ip") <> "" Then
UpdateHostCache
Status = "OK"
End If


The way it is setup Request.QueryString("url") is checked up to 4 times and ip is checked up to 3 times. I would suggest changing the behavior of 'UpdateHostCache' to return the status and replace the lines above with:
Status = UpdateHostCache() ' Return "" if no update
Response.Write Status


Line 251-270:
Function IsValidIp


Should add a little more checking. The way it is right now if I sent the ip 0.0.0.0 or 255.255.255.255 or 999.999.999.999 it would pass even though it shouldn't.

Need to block these ips also: 10.*.*.*, 255.255.255.255, 172.16.*.* - 172.31.*.*, 0.0.0.0. ip range 192 should be changed to 192.168.*.*


I did this too but unless you can think of a reason, I see no reason to store the ip and port separately.

Also, just curious but why no locks?

Hi tshdos,
I said in the readme that you should change the
default values due security measures.

No locks,
yeah... I had some problems with it.
I still have no real idea what locks are good for.
during the stress test me iis froze.
then i killed the locks and it worked.

thanks,
paradog

It looks like the reason it froze up is because you have functions that exit without unlocking the application ie:

Function asdf
Application.Lock

If A ="" Then
' should be an application.unlock here
Exit Function
End If

...

Application.Unlock
End Function


The reason for the locks is to keep the counts correct.
An example would be if two clients hit the following line at the same time.
Application("count") = Application("count") + 1
If you assume Application("count") = 0 before they hit this line two things could happen. Either it will work fine and the count will
be 2 or when both clients get the value of count before adding one they both get the value 0 in which case both clients set the count to 1. Honestly if you are not going to get a lot of hits at the same time you don't really have to worry about this, but it doesn't hurt performance if done correctly. You only need to when updating really.

I did not notice the line said '// Change default values.
But you should probably set the default to something besides 1 since most of the other functions use a 1. Just some advice though.

Thanks,
I really appreciate your help.
Would you like to code Lynn with me together?

If you want you will get access to my ASP Server too.
(Great server: The premium package of www.maximumasp.com)

Do you have ICQ? My number is: 94543674

Sure I will help. I don't need access to your server though. I have a few servers already.

I don't currently have or use ICQ. I might download it later though.

Well, thats cool.
I will try to fix that lock problem,
I dont really know how to validate an ip?
What range do IPs have?
Is it always from 1 to 255?

I searched for tshdos on ICQ and I found one are
you Kevin?

Well it is ok if I add your name on that
temporary homepage of Lynn?

For the purposes used here, it is probably easier just to compare the left n chars of the ip against the chars of the ip.
Example:

Public Const IP_MASKS = "127|192.168|(...)"

For Each Mask In Split( IP_MASKS, "|" )
If Left( HostIP, Len( Mask ) ) = Mask ) Then
'block ip
...

IPs range from 0 to 255. I am not sure if it is possible to have a 0 as the first number in an ip but it is ok for the others. I also think 255 might be reserved but I will have to check on that.


Yes that is me. I have not used it in a year or so. I assumed they would delete it after a while.

I have no problem with that.

well see you then.
could you gimme your email address?
mine is guox@gmx.net
