Web-to-Host Pro

The following apply to Pro Client sessions.

Security compatibility with other Micro Focus products
Web-to-Host 6.9.4 SP1 contains FIPS 140-2 compliant Security Services and supports Internet Protocol version 6 (IPv6)-formatted IP addresses for hosts.

As a result, Web-to-Host 6.9.4 SP1 is only compatible with Rumba+ Desktop 10.2 SP1 and Rumba+ Desktop FTP Client 4.9 SP1.

Using Pro with WTS/Citrix Server systems
To run Pro sessions (AS/400 Display and Printer, Mainframe Display and Printer, HP, and UNIX) through a WTS/Citrix multi-user system, you must first install them on the server.
  1. Log on to the server with Administrator credentials.
  2. Using the appropriate command, enable "install mode" (refer to your WTS/Citrix documentation for details). Using install mode prevents other clients from installing software at the same time, avoiding potential conflicts that could cause the server to go into unsafe mode.
  3. Open a browser and run the desired Pro session.
    Note: You must be in install mode the first time you run each type of Pro session.

Once the session files and components are installed, users must have the license required to run the sessions through their WTS/Citrix clients.

Password-level caching for AS/400
Since V5R1M0, the password level (QPWDLVL) for AS/400 hosts can be set to allow short or long passwords (1 - 10 or 1 - 128 characters). Web-to-Host sessions wanting to establish a connection to an AS/400 host must first determine (resolve) the password level the host is using. This can slow down overall system performance, increasing both connection time and network traffic.

To improve performance and shorten connection times, OnWeb Web-to-Host now caches password-level data by default. The first time the password level is resolved, the data is saved on the client PC. From that point on, each time the user connects to the host the cached data is used, eliminating the need for multiple network connections.

Cached data is host specific. Once the password level has been resolved for a particular host, it is used by all sessions connecting to that host.

It is strongly recommended that you not change the password-level cache setting. However, there are cases where it could be necessary. For example, if the password level of the host is changed. In that case, you may need to do one of the following:
Pro Display and Printer sessions:
Open the session HTML (<session name>.html) and remove the this.HostPwdLevel parameter.
Pro Display:
Open the session HTML (<session name>.html) and add the this.ResolvePwdLevelPolicy setting into the function stAS400DisplayProps() according to the following:
  • this.ResolvePwdLevelPolicy = 0 Means "Query and cache password level value once, and use it ever after". Default.
  • this.ResolvePwdLevelPolicy = 1 Means "Always query and cache password level value upon each connection".
  • this.ResolvePwdLevelPolicy = 2 Means "Never query host for password level value, and use the lowest password level value upon each connection".
Pro AS/400 File Transfer sessions:
Set the password level caching policy. To do this:
  1. Select Connection > Configure. The Configure dialog box appears.
  2. Click Security.
  3. On the Security page, select the option in the Resolve QPWDLVL System Value drop-down list.
