web_submit_data doesn't replay in LoadRunner script (LR 11.50)

Question

I have an application, which converts any long URL to short URL like this: https://{HOST}/short_link_name and my goal is to make working script.

User opens https://{HOST} in browser, passes the authentication form with credentials and sees the form for converting long URL to short URL. The form consists of 3 input fields:

{long_URL} - is any long URL which user need to convert into short URL
{short_URL_name} - is the name of link given by user for short URL
and the 3rd isn't important in this context.

Then user click button for submitting data and can see the result - short URL link below this form.

So, I made the manual script and the snippet of script is here:

web_url("{HOST}", 
    "URL=https://{HOST}/", 
    "Resource=0", 
    "RecContentType=text/html", 
    "Referer=", 
    "Mode=HTML", 
    EXTRARES, 
    "Url=//Grid/GetLinks?_dc=1383645884804&page=1&start=0&limit=6", ENDITEM,
    "Url=//Grid/GetLinks?_dc=1383645898655&page=1&start=0&limit=6", ENDITEM,
            "Url=/GetImage/Methodology?width=200&height=200", ENDITEM,
    LAST);

... (verifying that my username is displayed on the application page = I'm logged in)

web_submit_data("Register",
        "Action=https://{HOST}/UrlRegistration/Register", 
        "Method=POST", 
        "RecContentType=application/json", 
        "Referer=https://{HOST}/", 
        "Mode=HTML", 
        ITEMDATA, 
        "Name=ShortUrl", "Value={short_URL_name}", ENDITEM, 
        "Name=LongUrl", "Value=http://{long_URL}", ENDITEM, 
        "Name=Persistent", "Value=false", ENDITEM, 
        LAST);

Notes:

1) the values like _dc=1383645884804 are timestamp;

2) I'm logged in application page successfully;

3) https://{HOST}/UrlRegistration/Register doesn't physically exist in HTML-code of submitting form of application.

The problem is, when I run script, for this snippet I have ERROR with next text:

Action.c(65): web_submit_data("Register") started
Action.c(65): Error -26627: HTTP Status-Code=404 (Not Found) for "https://{HOST}/UrlRegistration/Register"
Action.c(65): web_submit_data("Register") highest severity level was "ERROR", 1245 body bytes, 287 header bytes

The HTML snippet for this form:

<form action="/" method="post">
 ...
</form>

Why I have this error with web_submit_data and what should I do to get correctly working script? Could you help me, please?

With checked option "data returned by server" in extended log I have next:

Does the timestamp affect on error appearing?

Put "data returned from server" runtime log setting on and post the complete HTTP conversation — Gareth Davidson, Nov 04 '13 at 17:13

Rule of thumb: Record twice with the same user ID. Those items which change from one recording session to the next are not optional to address. This is per your timestamp labled items. Add a third recording under a different user ID and this will expose items which are account specific which need to be addressed.

Yes, I see that timestamp is changed from record to record, and if I put strings with timestamp in /* */ errors appeared connected with this place of script. If I save current timestamp in a parameter and then use this parameter in web_url, I also have error. I have not yet figured out how get around this error. Thanks for idea about 2nd user! – Nadezhda T Nov 08 '13 at 10:23

Commenting out items which are in the request is not an appropriate development model for virtual users – James Pulley Nov 11 '13 at 13:43
