Can anti virus software block forms

Just recieved an email minus content.

Hi,

I just got an email from my sites minus the details of the sender. The form is set up such that you cant submit without entering some details. Twice in the last two days i have gotten blank emails but when i test it myself all seems to work fine.

The only possibiitiy i can think of is that I block the site access in certain countries and that some proxy accessor may have started the form process only to to have the proxy reject utlimate action on the form?

Any thoughts would be appreciated?

How are you checking that "you cant submit without entering some details"?

If you're only using javascript but not checking the details with the sending script then that'll be your problem - something is requesting the "send the email" script directly but since you're only running client-side checks and not server-side checks the script doesn't know it's only supposed to send an email is X, Y and Z are present and so will send you a blank email.

The script to send the email is called up using the onclick command or similar. It basically says on " btnsubmit " . I dont think that something external could call it up?

Do you have a confirmation page that comes after the submit? If so, what happens if you browse to that confirmation page bypassing the script?

Hi,

At the end of the script for the form i use the statement response.redirect which then sends the user to the confirmation page.

I take it you think that the problem is not an anti viral measure etc.

Thanks

Browse to that confirmation page directly in your browser. Does browsing to the page generate the empty email confirmation? Are you using an .asp script?

[irishaff]

browsed directly and nothing happened. Perhaps its that the Javascript that checks for data in the form does not work ( java disabled? ) . I am using ASP yes.

Hi,

I checked the logs in detail and it appears the user went through the correct channels to get to the page. Just thought it odd and worthy of mention, but am left with the feeling that its my set up. Was there any particular reason you asked me as it ASP?

Was there any particular reason you asked me as it ASP?

I use various asp forms. I've seen issues in the past with blank form submissions coming in. Certain useragents are going directly to the the confirmation page bypassing the initial page. Something in the script was allowing the email confirmation to be sent even though there was no form information to send. Long story...

Ok thanks. I wont get too worried about it , unless they all start coming in blank. I have seen proxy systems which do not allow the processing of the script and this alerted me.

Cheers
