( #3333=superdoc: print w/replies, xml ) Need Help??
Hi -

I'm using LWP::Simple to retrieve a number of pages based on user input. Because of the complexity of each page, my "roll a six to start" host, and the complex regexs I'm using, it takes a while. A long while. A very long while.

Now, I'm worried that Joe User will either:

  • Get bored and go away
  • Have his connection time out

So I'm looking to keep the user informed as to how the process is doing.

I've tried using JavaScript to put status messages into text boxes at the top of each page, but the Perl script seems to emit only "chunks" of text and doesn't send text line-by-line, so the status boxes don't change. Could this be related to Cgi-wrap? Or is it because Perl's waiting for the complete page-retrieval subroutine to finish before printing the text?

Thanks ppl!

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
