Mine Type

The eSO Setup sets a Mine Type (Link Handler) to the SOSigOffice.exe to start eSO with a Link. The URL is eso:// and it can also contain all the StartParameter of the SOSigOffice.exe. To seperate the Parameter a | must be used.

This is working in Offline Application and in the Main Browsers (IE, Firefox, Chrome, Safari, Opera), in most of them the User gets a Warning/Message which he needs to accept.

Sample

eso://	Starts eSO
eso://-pdf=https://www.stepoverinfo.net/eSO-Samples/Mustermann.pdf\|-sss=https://www.stepoverinfo.net/eSO-Samples/Mustermann.sss	Starts eSO with PDF and SSS, which will be downloaded
eso://c:\Mustermann.pdf\|-autostartsig\|-stayontop	It also works with local files

Registry Entrys for the Link-Handler (only required when not using the Setup)

To use that we add the following Registry Entry.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\eso] @="URL:eso protocol" "URL Protocol"=""

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\eso\DefaultIcon]

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\eso\shell]

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\eso\shell\Open]

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\eso\shell\Open\Command] @="\"C:\\Programme\\StepOver\\eSignatureOffice\\SOSigOffice.exe\" \"%1\""

Additional information for Firefox:

As of version 122.0 (currently the most recent version) the Firefox browser has a bug which deletes the colon in the PDF download path, which makes a message appear that the PDF cannot be found.

To fix this problem, replace this colon with "%3A".

So our example URL will look like this:

eso://-pdf=https%3A//www.stepoverinfo.net/eSO-Samples/Mustermann.pdf|-sss=https://www.stepoverinfo.net/eSO-Samples/Mustermann.sss

Additional setting for Chrome:

Open "Preferences" of Chrome, you can find it under %LOCALAPPDATA%\Google\Chrome\User Data\Default\Preferences

Close Google Chrome.
Open the Preferences file and search for excluded_schemes in protocol_handler.
Add the line
```
"eso": false,
```
to excluded_schemes.
Restart Google Chrome.
