Is it possible to have a script call a function or sub and continue
before that function or sub finishs it's task? Here's the problem I'm
having and what I'm trying to solve. My hosts SMTP server is being
horribly slow, on the order of 10-15 seconds to send a simple email. As
you can guess with the forum if it has to send 10 notices on a post it
can take as much as 2 minutes for the post_message.asp script to
complete. Is there any way to call the email function, or wrap the email notification section in a function or sub, to queue up the emails and finish the post_message.asp script before the mails are all sent? I'm not sure if it's even possible to execute ASP/vb script in a non linear fashion like that. Thanks for any suggestions (other than changing mail servers, I know that works but isn't a viable option right now). John |

i dont think you can do what you want,. if it is that slow it most likely is a big distance between the web server and mail server, as this does make the forum slower during postings., who is your host?, i would recommend looking for somewhere else if it is being that slow , it shouldn't take that long. |

It's a problem with their mail server that they don't want to admit
too, it didn't used to be that way. There isn't really a large distance
between the web server, hosted on my cable connection, and the ISPs
mail server. It used to be much quicker, say 1 second, as you would
expect. I can send mail through my own SMTP server but then I run into overly agressive spam filters that think they know every valid IP address and so on. I'm thinking the only way to do this, if it's even possible, would be to spawn a seperate thread, which may not be possible or may require a ISAPI control. It would probably be simpler to drive down to the cable company and fix their SMTP problem for them.  Thanks dj air. |

It does seem to be possible using MSMQ, next question is whether it's worth the effort or not for me to do it in this case. Here is an interesting PDF on a solution that creates an asyncronous emailer: http://www.digievo.co.uk/articles/asyncmailer/asyncmailer.pdf - http://www.digievo.co.uk/articles/asyncmailer/asyncmailer.pdf |

| It's easy to multithread in .net as I understand, but not ASP. |

| Yeah, in .net you can just call the sub asynchronously. You could do all your code for that page inside a VB6 COM Component and use threading, but that could mean a messy deployment. |

It turns out you can also do it using XMLHTTP by calling another
script. You can use xmlHTTP to do a post or get of another script and
not have the initial page wait for a response. While this method works
to get it to work with WebWiz would mean some passing all of the
sendmail parameters to the new script so it could loop through the
people to send email to. Here is the code to call script2 from script1 and not have script1 wait for script2 to finish it's tasks. Response.Buffer = True Dim objXMLHTTP, xml Set xml = Server.CreateObject("MSXML2.ServerXMLHTTP") xml.Open "GET", "http://localhost/somescript.asp", True Call xml.Send() On Error Resume Next 'Wait for 1 second to see if we've not gotten the data yet If xml.readyState <> 4 then xml.waitForResponse 1 ' After 1 second move on with the script End If Set xml = Nothing |

You might want to see if they allow you to use localhost for a mail server.
Some mail components also support queued mail. I don't recall offhand which ones do and which ones don't but for some reason I thing that AspEmail might. Find out which components your host supports and check the component site for details on queued mail. Usually just requires setting another component option or two. -------------
