Hello,
We have a form that bots are using to submit thousands of requests through POSTs. We want to add a check which would ensure bots do not auto-submit the form.
This is in Classic ASP on Windows 2012 R2 server IIS 8.
Attached are the files related to the POST requests:
2017-01-24 16:24:01 W3SVC118 flash [login to view URL] POST /[login to view URL] - 80 - 5.188.211.15 HTTP/1.1 Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1) ASPSESSIONIDSATSBDAA=DJHHALHDLPCCADDKBEPGBABC [login to view URL] [login to view URL] 302 0 0 420 2090 140
REQUIREMENT:
=============
- Complete in 3 days or less
- Code must be secure and optimized to work quickly
- simple CAPTCHA (nothing complicated, just something easy for clients to use)
- Code must be in ASP
[login to view URL]: The file on the website that is visible which has the Submit button
[login to view URL]: This is the file being POST into causing the spam issue
[login to view URL]: The file related to the one above that sends the emails
To qualify for this project, you must answer the two questions below:
1. Which CAPTCHA or verification technology you'll be using
2. Which files you'll need to edit to fix this problem
Hi,
I am experienced and certified Programmer. I know Classic ASP and various other programming languages.
Since producing images with Classic ASP requires paid/expensive third party components, I will be using Mathematical Captcha to prevent Spam. Mathematical Captcha is a simple math problem such as "How much is Two + 8" and "How much is 2+9". Bots are usually built to resolve Image Captcha and they fail to pass mathematical Captcha.
It can effectively stop 99% of the spam.
Thanks,
Amanat Ali
