[Xitami] Unconditional execution of a CGI in html.

The <image...> solution is going to be the only valid one that does not require user interaction or javascript.  And if your implementation of the <image...> method is producing an incorrect or empty image, then that merely implies your CGI script that generates the image is the source of the problem.  I am unaware of any HTML/CSS/Browser issue that woud not permit the image from being rendered properly.

However, if you continue to have issues I suggest you use a web design/html forums site for further support.  The Xitami forum is meant for server issues and server help, not coding problems.

> The "test" cgi program gets executed, the Xitami desired variables, etc. are recorded to a file on the Xitami Server. The files expected to be written by "test" are created with "open append"  and contain the information expected.

> In the mean time we decided to use the <iframme,,,> to display relative information sent to stdout by the "test" cgi program with print(i.e.) "Date and Time of visit". The print to stdout by "test" of this information is displayed in that iframme graphic at the Browser.
> Now, we did find the use of <image,,,,> will execute the "test" cgi but it displays an unwnated graphic at the Web Page Browser with nothing in that graphic.

> It would be nice to get the "test" to execute and not use any HTML that creates a graphic (<image> or <iframme>)or requires a user to poke on something (<a href> or <form field>)etc. using some other HTML.
