I'm working with an ecommerce API. Once the transaction is processed an HTTP post is sent to a URL of your choice with the transaction data (a way to confirm transaction on your site). This is fine, however how can I confirm the HTTP post is from the applicable source for security purposes? I tried $_SERVER['HTTP_REFERER'] but nothing is provided.

How to display html detail when clicking submipls

In internet explorer i am able to access a https site and download a file. i have to use an username and password to access the site first.
However, when i enter the URL and credentials in SSIS using the HTTP connection managerand press the test connection button,  i get the message:

The remote server returned an error: (401) Unauthorized.

Any ideas why this is happening. The username and password are correct.

Can i use an https site in a http connection?

Any help appreciated.

Thanks

I created an htaccess file in my directory for pma.fivetier.com with the following:

order deny,allow
deny from all
allow from xx.xxx.xxx.xx

Open in new window


When trying to visit from my IP I get a testing 123... page if you visit link above you will see.   If I remove the .htaccess file I have full access again without any problem.  What am I doing wrong?  Do I need to use ipv6 address or something?

Hi Guys,

We wrote an application that downloads json files down to about 80/90 client machines, we have reworked the mechanism but cant get it work correctly

I want to know how we could enable our server to send http status code responses then I can use the reponse.statusCode to see if a new file is available and make this whole thing a lot easier and more robust.

We just moved from WinINET to WinHTTP. The latter does not have an equivalent InternetCanonicalizeUrl function.

The WinHTTP docs say that WinHTTPOpenRequest does this automatically but there is nothing there that specifically addresses this.

According to this reference you can use WinHTTPCreateURL which uses a URL_COMPONENTS structure to define the various URL parts. In the latter the lpszExtraInfo property is where you put the ?param=xyz& ... part.

Here is my problem - one of the parameters in the paramter string needs to be canonicalized as it could contain non-URL friendly characters (Example &).

With the WinINET version we used InternetCanonicalizeUrl on the specific URL parts which were then appended to the URL string.

Example
If we have a URL now that looks like this
mydomain.com?param='Name & Surname','Description'

Open in new window

And we pass that to WinHTTPOpenRequest - it does not know that the & in Name & Surname is data and not a parameter separator.

Question:
How do we canonicalize individual parameters in the URL with WinHTTP

Hello Experts,

Somehow on some of our websites, the redirect to 443 was shut down.

How would you go about finding the missing redirects?

This is on Windows IIS.

The only thing I can think of is running scans on 80 and 443 and compare the two, but I don't think that will address the missing redirect. We do not have a Web Application Firewall to determine this.

Would the firewall reporting tools work? What the SIEM?

Thank you, your recommendations are appreciated.

We are looking for an FTP apps that we can click on a folder and get the total size of that folder, including its sub-folders; something like WinDirStat.  The most important is to get the size of the folders.  What FTP can we use?

Note: we are using FileZilla, but there is no option like what we want.

print_r($recsDNS);

Not getting CNAME records Properly, SOme times coming and some times Not.

If I use DNS_ALL :: After refreshing 3 to 4 times i am getting CNAME records.

Hi

I have an application that needs to connect to a third party server on HTTPS.

App server > Bluecoat device > Firewall > Third party server

Our Bluecoat team are saying they want to block application HTTPS connections because they can't scan them. Note browser traffic uses a different proxy. So we are going to configure our service to use HTTP.

Is there a way to have this converted to HTTPS?

I have a computer here that almost daily will stop bringing up web sites.  I've read more than I can even tell you and tried  everything I could to see some rhyme or reason why this is happening.  I can ping the address from a command line or the domain name.  Outlook isn't affected even though it's hosted offsite.  I can't access the web whether I put in  the Domain name or IP in the URL field.

I've flushed the ARP cache more than once, stopped and restarted dnscache, flushed dns, scanned for trojans, malware, etc.  And the only thing that will get it running again is to restart the computer or flush dns.  We recently went through a DNS server change but we kept the same IP address.  This also doesn't affect all the computers on the domain.

This is a Windows 7 Pro PC on a 2012 R2 domain.

I can't figure it out.  I am open for ideas.

Thank you!

I have finally been able to get a response from a API call and it now sends me back a response which has a Gzip file in it. How can I automate this in VBA to:
1. Decompress this response.
2. Decode it
3. Save it as a file for me to view.

Thanks.

Hi,

since we use Ubuntu 16 and Apache 2.4.18 the Status Code responded from apache is now:

200 200

Open in new window


instead of

200 OK

Open in new window


Our application is waiting for the "OK" and doesn`t work correctly with the status code "200 200".
Is there a way to tell apache to respond with "200 OK" again?

Many thanks in advance!

Hi
i am trying to get files name list from a folder which is on remote server using vb6.0
vb6.0 application will run on clients machine...
is there any possibility using http..?

Please note : there is no FTP, i dont have flexibility to use ftp, (only i need to use http or any other option except ftp)

kind regards

On a network, internet connection is limited this way; once you send data and receive reply , isp immediately resets the connection. HTTP access is possible, but HTTPS is seemingly not. Do I have chance to have HTTPS access over this network ? Do you have any idea ?
